Sorry for the delay kevon, i didn't see i had a message.
As far as the sound is concerned it seems to be a mixed bag as far as people getting it to work. The way i was able to get it to work was to get the 5 necessary kexts from the initial post. AppleHDA.kext (vanilla version), IOFamily.kext (vanilla), HDAEnabler, Verbhelper, and LegacyHDA. I used kexthelper to install all 5 of those, rebooted and mine worked.
Try rebuilding your dstl file using dellefi as well.
