Hey everyone. Quick question, can I buy into a btc mining pool? Is it like buying stocks? If so could you point me to the best pool?

PS - If someone else already asked this question, feel free to just point me to a link.

thanks!

Hello everyone! I've managed to get my hand on a pre-order of an Avalon ASIC 63 GH/s unit. Sorry in advance if this is a FAQ. I did a little googling and I read over most wikis I could find. I just still can't find good info. on set up of the software and the basic ropes of joining a pool with an ASIC mining rig. Do I just go off old information, is it the same? Anyone know a place to read up on how to get things going when it finally comes?
