Looks like a good start. I agree with the memory expansion to as much as you can. I expect that there are 6 memory slots and 3 are now being taken up with 1G sticks. You can either add 3 more 1G to a max of 6G or sell the 1G sticks and buy some 2G sticks that will get you op to 12G. This might cost you up to $350 or more depending on what memory you choose.
