You have got yourself a good deal on that boat - if it were not for the constraints of my job right now I would have been very tempted to outbid you. She has good lines and is a good layout for cruising with a good number of friends.
I have been trying to prepare an E35 for the north Atlantic crossing (my job is giving me little time for the work unfortunately), and I looked at Heart of Gold in October 2004 with a view to that voyage. I do not know what work has been done since, but it looks like not much; these are my thoughts:
She needs a LOT of work before attempting the trip. A LOT of work, it will not be possible to fly to Florida, pick her up and sail her away unless you can spend a good chunk of time there making her ready (I will not say how long it will take without knowing your knowledge base), and I would caution against having too tight a timetable before you know the full extent of the work required.
Engine: Unless you are good with diesels and transmissions, I would ask in the Gulf coast section on this site for a recommendation for a mechanic in that area. I would also ask about possible locations to keep the boat, the advert on ebay said you would have to vacate the current slip quickly, you may have to contact Sea Tow or equivalent to get towed somewhere else. The seller says the transmission needs work, and the diesel has not run it years, so the work may be significant. As I recall the fuel tank was in decent shape.
Rig: She was damaged by Hurricane Charlie in 2004, during which the mast tangled with the neighbouring boat, and the top of the mast was broken off. The ebay seller said work had been done, but since you do not know the quality of it, you will want to get it inspected; again, ask on this site for a reccomendation for a rigger in that area. The new chainplates that are pictured were done before the hurricane, so may contain hairline cracks. If the job was done well, everything should be OK, but there are plenty of cowboys in US boat yards that you do not want to trust with your life.
Deck: The non skid is not part of the paint on this boat, but a laminate glued down to the deck. It was peeling badly four years ago, and may have to be repaired before the journey if bad enough to have any risk of you going overboard half way between Greenland and Iceland. You may be able to just patch it for now. Ideally you would repair the soft spots in the deck at the same time as replacing the non skid (see my first post above), but that would not be essential for the journey - if you repair the non skid now you would not want to cut holes in it later.
Sea cocks: I no longer remember whether the original gate valves had been replaced, if not, add replacing the through hulls with sea cocks and new drain hosing to the to do list. (I think, stretching my memory, they had been replaced with ball valves)
Wheel: The cables looked original, they were in decent shape in 2004, but inspect them. You will want to have a tiller for emergency use, there is already a mount for it.
Anchor: My memory is she had a good CQR anchor, but the rode may need replacing. There was a roller, but I do not recall what kind of windlass, if any, there was.
Electrical system: This had some upgrades in the 90s, but you may find some of it is no longer working. You will need new batteries without a doubt, and may need to replace essential equipment such as lights.
Plumbing: She had a flexible holding tank loose in a cabinet in the head - not ideal, but it may work for the journey. It will likely take a lot of work before the plumbing works properly, but if you do not mind washing out of a bucket you may be able to leave it until you are in Norway.
Deck hatches: She has forward facing and not very robust hatches, designed for coastal sailing. Plenty of sailors have crossed the ocean with them, but if a wave breaks over the deck it could rip them off, and you would have one hell of a time trying to keep the boat afloat if that happened in a storm. They can be reversed with some fibreglass work, or, better, replaced with ocean worthy Lewmar hatches with considerable fibreglass work.
Portlights: They were leaking in 2004, and it is clear in the pictures they have been leaking for some time. They are seaworthy, but the sooner they are resealed the better.
Galley: Stainless steel insulation had been added in the 90s, but the fridge was not working. Nor was the stove, nor plumbing. Can you stand eating cold tins of food underway?
Extra equipment: I do not know your sailing background, but there have been discussions of essential items for ocean crossings on this site, and there are many books on the subject. Usually, such things are cheaper in the US than in Europe, although the dollar has strengthened a lot in the last year.
Finally, I have heard of boats being shipped by container, so it is possible, but I have no idea how much it would cost to ship a 17500lb 41' boat.
I hope that helps (your English seems very good, but do not be afraid to ask if there is anything you do not understand). I recommend you take a digital camera to look at the boat, so you can post pictures here of anything you want to ask questions about.
Good luck....

. I am really looking forward to using her, but first the engine and transmission will get some servicing. I live in Norway, so it will have to make it over the Atlantic on a ship or on her own keel.
