I am participating in mining pools right now, I'm getting some bitcoin. How do I obtain a block needed to collect transaction fees? How can I tell if I have one already? I generally transfer everything to a master wallet, would a block transfer that way as well?
I'm not quite sure what you mean by this question. If you're speculating, you don't need to solve a block yourself - all you need are coins. You can buy coins a number of ways - through exchanges and also businesses specialising in selling bitcoin.
If you did purchase an entire block's reward (50 btc at the moment), you would simply have it transferred to you wallet via an address you'd give the seller. You could approach pools if you need a block's reward (rather than just 50btc in random coins). They'd probably want a premium though.
