Recommend some programs

I've been using the same programs for a while now, but they are starting to annoy me. Suggest some substitutes:

WinRAR. The splash advert is evil as fuck. I need something free that works on a wide variety of archive files.

Winamp. Back in the day, it was relatively lightweight. Now it takes an eternity to load on my laptop, if it doesn't crash first. Since I need something fast and lightweight for the laptop, suggest something like that.

Opera. You know, I was using Firefox for over a year. Then I tried Opera. I like it. It has a lot of stuff at once. But I'll be damned if it doesn't crash all the time. I'm thinking of going back to FireFox, but is there anything I should know about Opera crashing so I might can solve this myself.

Trillian. I like it, though it may be time for a change for me. Any other good messaging programs out there that support a wide variety of connections at once?

I'm not trying to start a flame war or anything. I just want to use the best programs.

Miranda unfortunately requires you to do much customizing before you can really enjoy it.  One of the things that made me use Miranda though is that it supports MSN v10 whereas libgaim probably won't support it for another two or three years.  MSN v10 was a biggie for me as all my friends use MSN.
