Trade skills (am i missing one) ?

Alchemy: No reason to have with your main group. You can have another 70 alt mail potions and transmutes to your team.

I beg to differ all five of my toons are 375 alchemists. The +63 spelldamage trinket is pretty nice as well as getting more mana back from mana pots. Having 5 transmutes every day is really nice also. Time will only tell if there will be another money making transmute in wotlk (my bet is there will be). My orginal plan was to do leatherworking * 5 but I figured out I could be getting better gear with badges than leatherworking.

Having every profession sounds pretty cool. But what is the point? Getting a server first recipe to drop will make you alot of money if you spend alot of time in trade advertising yourself. But dailies also make you alot of money. I was able to grind out money for my epic mounts within 30 days of dinging 70 (selling ~400 large prismatics helps).

Another thing you might want to take in to consideration is the rep grind needed for various professions. I about tore my eyes out when I was trying to raise my sporegarr rep for the transmute earth to water. It took a good 3/4 hours of repeating the same quest over and over. Now if you had to do this for 4 or 5 different factions I could find myself burning out very quickly.

the way I have my professions setup is

Shaone herb/alch
shatwo skin/alch
shathree mining/alch
shafour alch/nothing
shafive enchanting/alch

I would think your team is going to be better off trying to help themselves out with bop crafted items than trying to get every recipe in the game
