The mic100 only has balanced in/outs. If there is some specific reason you want to use this piece of gear then I would suggest you get a DI-Box. It takes a 1/4" unbalanced and gives you a balanced XLR output. The pre-amp is not needed in a functional sense for what you're doing so keep in mind, unless you're trying to get the "sound" of that piece of gear it's not required.
It's not required that you use a DI-Box but just plugging your guitar into something expecting a balanced input will kill about 3db (half the volume) and be a little noisier. Of course the manual for the mic1000 says you can just plug in a guitar to the input. Yet another reason Behringer is not a respected name in the pro community, unless it's their cable tester that works well.
Now the E-MU 0404 has mic/line inputs. The manual isn't clear and I don't see buttons to switch between mic/line on them so I would assume it's 1/4" for balanced "line" input and the XLR for the 'mic' input which uses a preamp. The mic input is not something you want since it'll be coming in way too hot for that at line level.
So for what you asked here's the cabling I'd use to connect your setup.
|bass|<--unbalanced 1/4"-----unbalanced 1/4"-->|DI-Box|
It's possible to use XLR - balanced 1/4" between the DI-Box and mic100 too because the inputs are wired in parallel. Same with the output you could also just use a balanced 1/4" to balanced 1/4" makes no difference. And of course as I said you could also just plug your guitar straight into the mic100 with a 1/4" too it just wouldn't be "right."
