[LAU] Preamp for mic/ guitar

Hi, First is it possible to reply a thread if you removed all the messages from your inbox? Thanks for the advices for me about soundcards, mixers, mics and preamps. I've bought a m-audio audiophile 2496 and a shure sm 58 and today I got a M-audio dmp 3 by post. I couldn't find a dmp 3 second hand in europe so I ordered one from the Us :p ... Today the postman arrived and he asked 25 euro's import costs :( That makes the dmp 3 117 euro's for me... if he works well it's better then the 160 euro's new ;) Are there things I should take care of when I'm gonna use the shure sm 28 and a guitar with the dmp? The mic and guitar doesn't need phantom power is it? Other things to be alert of? Thanks in advance, D
