Maybe you have to clear all .fas and .lib files built with the old
clisp. You may have to do the same with the directory ~/.cache/common-lisp/... 
before building clx and clfswm.
In all cases, when something goes wrong with CLX, start with a fresh
source directory and clear your cache.

I think so.

SBCL takes a lot more memory than clisp. _Maybe_ you have some swap
problems. Can you search the cpu and memory used by clfswm with sbcl?
Also, Flash is known to use 100% of the cpu.
What hardware are you running clfswm on?

This one is because you haven't enabled local connections on your X
server. Add a line with 'xhost local:local' in your ~/.xsession or
.xinitrc or .Xclients.

Ignore this for you!!! I have it running here with clisp-2.49 and its my
everyday use case.

I'd like to fixe them but I have clfswm running here with clisp-2.49 /
mit-clx, new-clx and portable-clx. It runs also with sbcl-1.0.45 with
the patch [2] and with sbcl-1.0.46 with the original clx-0.7.4.
There is surely some bugs in clfswm but those you have comes from your
CLX installation.
