Got Adium. Love it. Handles multiple logins to .mac accounts as well as everything else. Also, just installed Gizmo who used to have a plugin for adium. Currently on the backburner but will be interesting to see what it can do when it is relaunched.

Never heard of textmate. Will check it out.

And yes, lightroom and aperture does blow iphoto out of the water. 30 day trial for lightroom 1 (commercial release - not beta anymore) available on adobe.com Waaaaaay better than the beta release.
