In Audacity 1.3.12 you can just Import (from File menu) your tracks into Audacity. Audacity will support multiple sample rates in the same project.
When you get round to Exporting (from File menu) your finished project (to create a normal audio file from the Audacity Project), look in the bottom left corner of the main Audacity window and set the "Project Rate" to 44100 (or whatever you want for the finished file). The exported file will use the Project Rate setting.

That will simplify things. 44100 is the standard rate for CDs and is the most commonly supported format - "44100Hz 16 bit (Microsoft) PCM WAV" should work with virtually any other program.

Noise Removal can work very effectively if there is a constant low level noise. If the noise is not constant or not low level then the effectiveness becomes an unpleasant compromise. Minimising the amount of noise in the original recording is much more important than trying to fix it after making the recording.
To minimise noise, use the microphone close up (you may want to use a "
pop shield" to avoid blowing on the microphone). Set the levels on the mixer and the M-Audio Microtrack II carefully so that you have a strong signal (but not distorting) both in the mixer and on the Microtrack.
Gate vs Noise Remover.
A "Gate" (Noise Gate) is a simple effect that gets its name from the idea of a physical gate. When the gate is open, things can pass through. When the gate is closed the path is blocked. For a "Noise Gate", the level of the audio determines whether the gate is open or closed. If the sound is below the "threshold" level, then the gate closes and mutes the sound (does not allow the sound to pass through). When the sound level rises above the threshold the gate automatically opens and allows the sound to pass through.
The Noise Removal effect in Audacity is a more complex effect that uses a gate and other processing to reduce noise. The noise profile (which you must make from a representative noise sample before applying the effect) is analysed and the effect attempts to remove any audio that matches this profile from the track. This more complex method can be more effective than the simple Gate effect, but in some cases (depending on the actual audio) the side effects (wobbly bubbly electronic sound) can be too distracting, in which case the simple gate may sound better.
The Noise Remover can give a smoother shave than the Gate, but is more likely to remove a bit of skin in the process.
