Unless you have a real love of your current head unit i think it should be consigned to the bin as you won't be using it much for the next while.

Buy a seprate amp and run the empeg through that unless you already got one.

EAC is a nice ripper that works fine with lame but if you want a quick and dirty solution use something like music match just be prepared to redo it at some point but the quick and dirty will get you running
