Any Team can team up , unless it says not in the rulebook.
Genestealers are 15 points for one without any upgrades.
In Warhammer 40k there are Thunderwolf Cavalry with Space Wolves (although there aren't any models for them, you've got to build them yourself) and in Fantasy there are wolves that are ridden by goblins in Orcs & Goblins
The best website I know of is ebay, I really don't know of any specific websites that deal in just painted 40k models.

AnswerWarhammer 40,000 (informally known as Warhammer 40K or simply 40K) is a tabletop miniature wargame produced by Games Workshop, set in a science fantasy universe. Warhammer 40,000 was created by Rick Priestley in 1987 as the futuristic companion to Warhammer Fantasy Battle, sharing many game mechanics. Expansions for Warhammer 40,000are released from time to time, often to facilitate a certain sort of game, such as Cities of Death, Planet Strike and Apocalypse, which give rules for urban, planatary siege and large-scale combat, respectively. The game is currently in its fifth edition.

No. I do Warhammer and I originally thought that it was a nerds only thing. This however is a completely untrue stereotype. There are actually many girls who do warhammer, a few tradies, policemen and your regular people. Many fathers get their wives and eventually kids hooked in to it aswell. Saying Warhammer is for nerds is like saying that anyone who does any of the arts are nerds aswell. Warhammer is about sculpting, creative ideas, converting, landscaping, painting and strategy. You may think what you want, but is warhammer fans are nerds, than so are many, many other people.
