You do NOT need Xgl if you have an NVidia card. I actually uninstalled it on my system in order to keep the system from using it (it kept trying). Use the NVidia native support and that will work.
Also, OpenGL programs work absolutely fine, if Compiz fusion is configured correctly.
As for the emerald problem, need to see your error messages before I can offer an opinion.
edit: This is a script I found and downloaded off of the internet to start compiz-fusion. I then hacked it to deal with particulars of my system, which has an NVidia 7800GS video card and a 22" widescreen monitor. I also eliminated Xgl from my system.
If you know bash scripting, then my hacks should stand out - I didn't delete the code, just commented it out, and I forced the results I wanted - so if you need to alter it to work for you, then the way should be fairly obvious.
Using this script solved all my compiz-fusion startup problems on my Mandriva system, configured as I described:
