As far as bag space goes - get them all 16 slotters ASAP, then just filll up the main toon with crap, trade it off to an alt, etc... until your entire party if full.

If you have to, mail stuff from one toon to the next to free up bag space.
This.

As for professions, I recently started a 5 x hunter group and I went with:
5 x Engy - for Jumper Cables
1 x Enchanting - for DE'ing unwanted greens & blues
1 x Mining, 1 x Herb, 1 x skinning - the obvious gathering professions. Mining is on my main, since I don't want to miss any mining nodes (providing mats for the 5 engy's).
1 x Leatherworking - for drums of panic, BOE epix, armor kits

Cheers,
Stealthy
