Sorry Eon,
I'm silent on this one because I've recieved three different results from testing the install process. I have it working on a rack server I use for personal consulting, though is has tons of disk, multi cpu and scads of memory it has a minimal vid card though so I only tested the install pocess and running a dedicated server. Went very clean no problems. Also, the VMWare testing I've done so far has been pretty straight forward.
The Win98/ME problems are very indicative of of the OS, rebooting between major changes is the norm. Failing during an install / patch can set you back to the beginning so on those OS's, it's a safe bet to reboot between major operations. I have no idea but I'll be surprised if you can install
128MB ram should be plenty. I ran my VMWare system with that. Ghost mechs firing I think had nothing to do with CPU and more to do with an incomplete patching process that left me without texture art work. I have never had ghost mechs, I was able to see new mechs just fine.
BTW MT, the new mechs did look good!
I don't have anything to say about damage on new mechs, testing that in an online game is a poor test. LAN play with targets sitting very still and while moving would be more appropriate, they did this type of testing, I haven't. I may just suck at targeting these mechs. I have somehow, memorized torso sections to shoot at on the old mechs. I'm lost on how to kill a Marauder in 2 shots. Beaning it on the nose didn't have the effect I had hoped for.

The jumping Urbies died quite nicely though.
My overall impression is that if you had the HudPatcher and used it for many different things (something I had done) that you will have problems. I have no idea if the MercQ Skin tool has any effect. I messed around a lot with that as well.
