well this is when things can get kind of difficult. if you have a loop at a set speed, to pitch it up or down will of couse make your loop invalid. so then there is the pitch shifting algorythms on the emu, but that can create artifacts like timestretching things.
what i would try to do is play with it until it sounds good to me, but you another thing you can do is send the loop to an editing software like wave lab and do a spectural analysis. what you want to look for is the lowest frequency that is represented. that will be your fundemental, in other words, what note the guitar is playing at that given moment. you should be able to see each note as the fundementals move up or down from time to time. also, you can use the time grid to figure out where the notes are.
once you have established notes are being played, do the same with the vocals. then figure out what way you need to go. this is where music theory comes into play. but this can become even more complicated.
the best case scenario is that you are off a half step, from there you might get away with pitching the samples in your sampler, but remember, in order to boost an octave you need to pitch by 1200 cents. so if you are off by a half step, (c and c#) you would have to pitch by 100 cents. i think in this case i would pitch the vocals.
play around by ear or do the spectral analysis or trash the vocal and get someone you know that can sing and have them sing it in the right key.
perhaps some one has a better idea that i haven't thought of. this is the two likely courses of action i would take in this given situation though.
