Not sure what ^^ up there is flappin about but there are some goo recommendations here.
Trillian was the free app on amazon a couple weeks back, I picked it up as one of those you never know apps. It was free and you never know when it can be handy. It works for almost all chat programs including facebook chat. The only downfall I see is it doesnt support skype chat but /shrug.
As for twitter I use plume (formerly Tourtier) paid version. Other people use the stock installed one twydrod (i think), seesmic, and tweetdeck. Truly for those apps it is best to test them out and see if they will work for you. I use the android fb app for that so I cant comment on how the other apps integrate with it. However I did use seesmic for pc and sorta liked it.
