Not sure about the first one... but the others are known issues to OSx86.
2. Is your TSSTcorp DVD+-RW TS-H653A a SATA drive? is your SATA controller a NForce Chipset? MeDevil's kext is the one in use by all distros to support it and doesn't allow DVD writing... I had to buy an external to Write.
3. MSN messenger hasn't ever worked... if you search this forum back to its roots (around January of this last year) you will see its been that way since then and even before. (Same thing found over at InsanelyMac)
4. Some USB controllers aren't supported to be the new high-speed 2.0 and so you need to look for the 2.0 USB fix. I used to know where it was at, but not at the moment... if I find it, I'll post back here for you.

As far as the other issues you've mentioned in your earlier posts:
here is a good site to check out. It was created by Zephyroth and contains the section: "com.apple.GeForce; com.apple.NVDAResman Kernel Panic Issue" and explains why you get that kernel panic.

I've modified this section to take care of another issue as well... the "error loop at account creation"

my modified how-to simply goes:

• immediately after rebooting from your installation boot with the -s flag.
  /sbin/mount -uw /
  passwd root <- Hit enter and type any password you want then enter again
  touch /var/db/.AppleSetupDone
  rm -rf /System/Library/Extensions/GeForce.kext
  rm -rf /System/Library/Extensions/Ge*.kext
  rm -rf /System/Library/Extensions/NV*kext
  rm -rf /System/Library/Extensions.mkext
  reboot
  boot with -f
  create a user account
  install the Zephyroth Nvidia Universal Installer customized to your system.
  reboot
