hah - it took too long to type this ... trickdhat got in first. Maybe my list will help too - looks very similar.

Screw link to connect main central loop on harness with GriGri (I prefer the triangular style to the oval style because it gives more room for other things connected to this loop):
Made with a wide opening for use with rope, the Petzl Triangular Screw Link is a compact, lightweight alternative to carabiners for semi-permanent attachments.

Ascender (just need one - get the left one if you're right-handed and vice-versa - you'll probably prefer to pull down on the climbing line with your stronger arm):

locking carabiners:

I use an
auto-locking one like this for attaching the GriGri to the main loop on my harness:
The Petzl AM'D Triact is an asymmetric (D-shaped) aluminum, autolocking carabiner that's best-suited for connecting a belay system or for holding equipment.

I use these a pair of these
magnetic auto-locking ones for attaching my around-the-mast lanyard to the sides of my harness:
The Black Diamond Magnetron RockLock locking carabiner uses the power of magnets to give you the security of a locking carabiner with incredible ease of use.

Also: You'll want to get a few additional life-rated carabiners for miscellaneous tasks and back-ups (basic screw-gate and wire-gate types).
- Don't take any non-life-rated carabiners up the mast.
Small open-top pulley for the climbing rope turn at the ascender:
This super-compact, ultralight pulley with fixed side plates is very easy to handle and convenient to carry on a harness while ski touring or mountaineering.

Large oval carabiner (to connect the small pulley with the safety hole at the top of the ascender):
The iconic Black Diamond Oval carabiner stands the test of time. Now updated with a snag-free keylock design, this symmetrical carabiner with a large rope-bearing surface is even easier to use.

Foot loop: (I actually use two, but you can use just on - on your stronger leg) - there might be other cheaper versions
Climbing line & note:
- get a length of rock climbing line that's ~8-10' longer than the height of your masthead above the deck
- make sure it's size is compatible with the specs of the GriGri (and the small pulley)
- I think I got Bluewater 10mm
- tie it to your main halyard with a bowline-to-bowline connection (don't use the halyard's shackle), haul the halyard all the way to the masthead sheeve and tie it with reasonable tension and very securely on-deck, then climb on the climbing line: the ascender has very aggressive teeth that will wear out your halyard.
- Don't push the ascender all the way to the bowline a teh top - leave about 2-3" above it on the climbing line ... you'll need this gap to disengage the ascender when it's time to come down
