Here's a Screenshot of my Activity Monitor, anything look strange?

[Grateful11]

I'm just been having a lot problems lately, it won't go to sleep, I can't change the aspect
ratio on my Desktop Pic, overall sluggishness, just numerous little nagging items.
No panics or anything like that.

I've got 3 items listed on my Startup Items > Accounts Preferences:

iTunesHelper >Not sure why that's there.
MicrosoftMouseHelper >Probably need it, I have a wireless MS mouse.
Epson Scanner Monitor >Not sure why that's there.

I didn't choose any of these items for Startup they must have defaulted there.
The only one that's checked is iTunesHelper in the Accounts preferences.

I'm 10.3.9 on a G4 533 dual with 1 gig RAM.
