The point in clan, basically, is to eliminate the randomness, and team up with a bunch of guys that more or less share the same ideals (can be both game wise and other ideals). Then you can start doing competitions, practice on teamwork, tactics and strategies - but best of all, is that there's always a good friend with whom to play or chat.
All the alliances/wars bit is a bit hyped imo, and not necessary. Clan wars can go FUBAR and everyone get's hurt.
Anyway, I suggest you figure out how much time you'll be willing to spend playing this game. And if you want to commit yourself. If you want to play a lot and want to commit yourself to a greater enterprise - you are ready for clan shopping.
Good luck
