you have so many options... any wav editor can do it(soundforge, cool edit)... most sequencers can do it(cubase, sonar). even if you dont have those programs you could throw it on a cd deck you have it do what you need to. although i think you'll find time stretching will probably get a more desired effect

Project 7, grab the ancient little app Goldwave 4.19. Newer versions exist, but I've never liked them. Anyways, it has a "Playback Rate" option under the Effects menu. Unlike Soundforge's pitch shift, which can only increase or decrease in increments of 1 (which I find not precise enough), Goldwave's Playback Rate lets you adjust the tempo as precisely as you want.

changing the tempo is a whole different story then BPM, ..all time streching does is change the sample to the desired bpm...but you want a TEMPO change...this can be done by choping the sample up into many bits and placing them to your desired tempo..also you say you want to change the pitch, well you can use the pitch shift function in Cubase which has the Mpex algoryhthem that is the most lossless picth shift you can get.

I'm not sure if you mean tempo in the correct manner of speaking? if you do, then do what I said...but if you just mean getting the sample to the proper beats per minute then do what everyone else said. Using cubase is teh easiest.
