I used to use roboform for passwords. I don't anymore because I had two copies (a flash drive copy and a hard disc copy) installed for awhile and the .dll's were having some trouble getting along.
Broke the habit and use my head as well now

. But it's a good option.
Here are some other things I do:
I use a google spreadsheets plugin for wordpress to keep track of links sold. I could use a better plan for remember they are expiring, but this is better than what I had goin' on.
I use a project manager to organize what I have goin on and when.
I print every months affiliate statement, and paypal statement. + I have big plastic envelope where I keep every receipt. I write on the back what I bought if it doesn't say *pencils* etc.
