Finally synchronized the blockchain, yet not sure if I'm mining for coins. Where do I find out if I am or do I need something else?
1Do you want to mine?– user6398Sep 15, 2013 at 17:37
3If you're wanting to mine, please understand that you're unlikely to mine profitably unless you have specialized hardware or a high-end graphics card. In the latter case, you'd not use the Bitcoin-Qt client itself for mining, but a separate program such as GUIminer.

Graphics cards will not pay off any more unless you have free or very very cheap electricity.– Piotr KulaSep 16, 2013 at 15:45
The bitcoin wallet is for receiving and sending bitcoins. When it is synced you are all set. You don't need anything else to receive and send coins.
Note that you can receive coins even if the wallet is not synced, you just won't see them before you are synced.
I assume that you have downloaded Bitcoin-QT, the standard bitcoin client. This enables you to manage your addresses, to send and to receive Bitcoin.
If you want to mine bitcoin you will need special software, and if you want to mine bitcoin profitably you will also need special hardware. There is numerous questions about "how to mine with X" on this site, if you want to get started with that. See for example: How can I start mining Bitcoin?
