I do not live in Tampa, I have just been there with work, but if you want to talk to any locals try the 'Southeast and Gulf Coast' section, there are some extremely knowledgble contributors from the Tampa area.
With respect to the deck, what I would do for a long term solutiion is peel up the non skid, repair any soft spots, and then use a non skid paint. Painted non skid lasts longer thn adhesive non skid, as the sun acts as a solvent to the adhesive (that will not be quite the problem in Norway that it is in Florida of course).
If you just need to repair some small areas of the non skid before sailing the Atlantic, the pictures suggest the seller may have made similar repairs and know what to use, probably something like this:

I have never used that myself, but it looks suitable.
I did not see amy structural damage at all to the hull or deck from the hurricane, although I did not see below the waterline. The possible cracks I spoke of were in the rigging, hairline cracks in the coated surface of fibreglass are not a problem.
With respect to the chainplates and hairline cracks, you do not want to run any risk of the mast coming down in a storm off Greenland, so unless the previous owner replaced them in 2005, I would replace the larger chain plates that hold the main shrouds to the top of the mast. Take the old chainplates to a machine shop in Tampa and ask them to make duplicates. Stainless steel is expensive these days (the Chinese buy a lot of it) so they may cost about $100 each. Stainless steel is quite brittle, so it is possible for them to be damaged without obvious sign, so I recommend replacing them just to be sure. The smaller chainplates, for the intermediate shrouds, I would inspect closely with a magnifying glass for any signs of cracks, and any sign of bending, and if they are OK then you can leave them.
I am assmuing the shrouds were replaced when the mast was repaired in 2005, in which case they should be OK.
Something I forgot to mention yesterday was cockpit drainage, a subject we have discussed here a lot in the past. Ericsons were designed for coastal use, and for ocean use you should add more and larger drains in case the cockpit fills from a wave breaking over the boat. Keeping a boat hauled out on land can be expensive, but as you say you will need to be out of the water for a while, during which you can inspect the through hulls and add extra drainage (if you are not familiar with such work, get a fibreglass expert to do it for you). You will almost certainly need to sand the hull and apply new bottom paint, which is an easy if messy job. You may want to ask boat owners in Trondheim what type of paint they use there, since the growth will be different to the warm waters of the Gulf of Mexico. Also inspect the propeller shaft seal and cutless bearing before you go back into the water.
I hope you are familiar with the technical terms I am using, otherwise perhaps Sven can help - there must be a Norwegian name for shroud (as old as horned helmet, axe, and pillage), and pcitures must be available for cutless bearing, chainplate etc.
