2. A video card is a graphics card.
3. 350 khash/sec is way too slow for bitcoins. You also need to make an account on a mining pool to send coins to/from, for example on slush's pool. Then just input the login settings into guiminer.
Okay, I set up a Slush Pool account; I went to their website "mining.bitcoin.cz" and made an account, though I have 2 usernames and 2 passwords; 1 to login into their website, and 1 to put into guiminer.
I tried copying and pasting the address they gave me into guiminer, stopped my mining and restarted it with the new username and password they gave me.
In the "My Account" section, I was asked to input a "Bitcoin Address." Stumped, I tried imputing my email address twice but that didn't do anything.
My guiminer program is still running but the "My Account" section lists "0.00000000 BTC," even though it's been running for 2 hours.
I'm pretty sure the Bitcoin address is your wallet address. It's a long sequence if numbers and letters. Have you set up a wallet yet? I use Bitcoin-qt but there are others. Electrum looks good, but I've not used it.
You could probably run your laptop for the next 2 years, never mind 2 hours without seeing a change to your BTC balance.
