If I find a block solo I get 50 BTC if I'm in a pool do I still get 50 - fees?
If you are mining solo, you receive 50BTC + Txn fees for the block.
If you are mining in a pool, the pool divides up the 50BTC among the miners at the pool. (In one of many ways which pays more to the workers who did more hashing.)
If you mine in a pool, and find a block, you have no way to claim all 50+BTC for yourself. It is always divided among the miners in some even fashion.
