That should be fine for starters, although you'll hear incessant bitching aobut behringer gear on this board (some of it from me, i'll own up to that) but, at the end of the day, you work with what you've got until you can afford something better.
You've got 8 direct outs on the back of the Behringer, plus your two main outs. If I were you i'd be taking these 10 signals as your inputs into the Delta.
This way you can use the 8 directs to record "clean", then, if you want to use the Beheri's in-board FX, you can make a mix of the effects and send it out via the main buss (or any of teh auxiliray busses if you so desire).
The only other thing that would get you to a "bare minimum" standard would be a decent audio program. I hear that Audicaity is free, but if you're going to spend some money there's a few choices out there. Most programs have aa free trial version available online, so give them a try and see what you think. Choosing an audio editing program is like choosing any other audio equipment- diffrerent people like different brands/products becuase they suti them better. I swear by Cubase, but you may find there's other people who hate Cubase with a passion, and will call you "gay" and "a noob" if you use anything other than Pro Tools...
There's also the computer forum here, you can ask around there for opinions on different software.
Have fun
