Hi from Troy
wow, lots of questions - I will try to answer some of them as best as I can for you
Bootloader is a personal preference (mostly) - Chameleon, Chimera (which is the one I use as it has built in graphics information for my nVidia card), have not pleased with the Clover bootloader before. To get / make a custom DSDT for your specific motherboard you will need to download a program called DSDTSE which is freeware and will take the hastle out of making your customised DSDT for your specific motherboard.
You won't be able to see your mac partition / drive when you have booted into your windows drive / partition because there is no native support for the HFS+ filesystem (which mac os x uses) in Windows. To gain access to the data on the mac partition / drive you will need something like Mac Drive for Windows (Commerical product) or you could use a program called HFSExplorer which is freeware and also runs on Windows.
As for getting your sound card to work you will most likely need to download a program called VoodooHDA which tries to be an all-in-one sound card driver solution for OS X.
Dealing the the Kernel Panic - a screen shot would be great to see to figure out the error that has caused the panic
Hope this all helps
