Yep, that will work, as long as your burning software supports that drive, Toast should support it.
Speeds will be normal, after all, the cd-rom can only steal <2mb/sec from one bus.
The turbo max has 2 busses I believe, so support for 4 total drives, 66mb/s on each bus.
If you have a spare audio connector, you should be able to connect it to the cdr and have it work.
For optimum performance, I would keep the bigger/faster hard drives as the master of seperate buses. Put the weaker hard drive and cdr as slaves.
