Hi. I got an uberspecc'ed eMac G4 with an user-installed 2GB of RAM and 250GB of HD. The HD is divided in 4GB as a "shared partition (can't be made bigger b/c it's used as a share point for my sisters Windoze PC and Windoze acts funny every time I try to access a shared drive bigger than 4GB)", 30GB that I left as the root partition for LFS, 1MB for yaboot (that bootloader is very nitpicky with it's partition size), and the rest for OS X Jaguar (The Panther and Tiger Finder suck donkey balls), my apps and docs. The question I have is. Can I use OS X as a LFS Host? Will be damaged my OS X install? Will the LFS install be broken because I bootstrap/chroot from an OS X install?

You can install LFS just fine on a Apple with Mac OSX and it will run fine, just make sure you have the proper tools for building the toolchain on your base system.
