allllllllllllllright-eeeeeeee then

The behringer board you have mentioned will work for what you want to do for now.
First off, to clarify.....
The term monitors refers to TWO things really, and i didn't clarify.....sorry
Studio Monitors are a very special kind of speaker, designed for a very flat frequency responce and "near-field" or close up listening.
PA floor monitors are a different animal all together.
The term DSP means "Digital Signal Processing" and usually refers to onboard effects, such as reverb chorus etc....
now then
Because your board is "POWERED", you will need to get a set (or at least you can get by with a set, because they are generally cheaper) of PASSIVE monitors. Use the internal amps to power them, and use your line outs to feed the MR-8. There are a lot of them out there, and at least one user here on HR.COM is a dealer for the Wharfdale's and will make you a hell of a deal. (just search)
Don't try and use the studio monitors for PA use. The studio stuff is designed for listening to up close, and not for projecting a sound farther away. You will need to get a set of PA Speakers also eventually.
hopes this helps to get you started.
just to let you know, i now have 2 stereo amps in my studio. I feed the output from my behri board to the MR-8, and the main out to my first amp and speakers. These are swithchable between several sets of speakers, from a set of Bose, a higher end of Memorex, and just a coulple of "junk" speakers to compare the mixes on. I also have the Control room out ran to another amp, and into a set of ALESIS 1 monitor speakers for my C/R stuff, main mixing, solo's and stuff like that.
good luck with your recording stuff.
