1. Nope, Just slack for me.
2. I'm currently using swaret, but since slapt-get seems to be so popular maybe I'll try that one out. Although, I haven't had any problems with swaret, oh well...
3. I generally dislike gnome but I have dropline installed for one reason. (I never log into it but...) I have a piece of software (only one) where the gnome version actually works better.
4. Sadly, I use more non distro packages than distro packages I think. Especially now that I upgraded to KDE 3.5.1

Update
1. Still sticking with Slackware. I'm using version 11.0 now. But I'm also interested in trying out Solaris (Gosh if only I didn't partition on using primary/secondary. I really should have used logical, oh well)
2. I have decided to use no package manager, when I want something updated I'll do it myself and when those updates need new dependency updates I'll update those. That is the beauty of slack over rpm distros (don't know about apt-get distros), if you need to update something major like gcc you don't have circular reasoning problem (you can't update program x because you need to update gcc, can't update gcc because program x and y rely on gcc.)
3. I use dropline gnome but only for two reasons. A program I run requires all current gnome libraries to work. All other slackware gnome flavors are not as updated. But I can tell you from experience if you install dropline don't uninstall it. You will spend more time putting your system back together than if you just leave it alone.
4. I tend to find myself using less non distro packages as that all of the packages that I used before it seems Pat is including. The only program I wish Pat would include (mostly because it's a pain to compile) is mplayer. Otherwise I use a lot of java programs but they are not incorporated into the system they just sit in opt so I don't consider using that software as non distro. They are part of no distro.
