None whatsoever.
I found 2.4 more stable as guest than 2.6, but I prefer 2.6 as host...
Your call.

Skas is a patch to your kernel, but if you can't compile your own
kernel, try to find one ready-made from FC2/3.

Any recent kernel will do, don't use RH8 - it is well out of date.

Don't know about that. con1=ttyS0? then use vc/1 inside uml (wild guess)
