How do you organize yourself?

I am having some small trouble organizing myself as I reach over 10 autoblogs. Here are my problems:

1) How do I keep track of all my autoblog URLs and such? Should I save it in a excel file?
2) How do you guys organize yourself when it comes to plugins? Lets say you want to add a new plugin to all your autoblogs because you heard it is going to give you 2x as much traffic that you are getting now. How do you manage to add it to all your autoblogs if you have over 25 of them? Do you suck it up and do it manually?

there's a web service namely wp controller or something (you can search at google) that can do install a plugin to your all your WP site at once or controlling some wordpress site at once.

I use excel to log everything for each site.

Excel helps me out a lot when organizing stuff and even more; Google Docs.
Mainly because I'm working on this internet business with a good friend of mine. Useing G.Docs is great for this since you can work in 1 doc together and you can use it everywhere. (no need to email files back and forth, etc.)
