Your mic seems like a fine one for the task at hand. Mind the sibilance and use proximity effect to your advantage (I'm offhandedly assuming that it's a cardiod only mic, forgive me if I'm wrong). Truthfully, I'm inclined to use large diaphragm dynamics for inexperienced VO artists, they are a bit more forgiving and eq nicely, but most any quality mic will do.
Make sure the level of your mic pre is set for the best quality. Note that this doesn't mean the highest volume. Route from your pre to a compressor to catch peaks and add coloration if you want.
Once the audio is in your DAW use gain and compression to bring the level up. Limit it if you have to. Don't go crazy and keep gain staging in mind. If your record chain is correct, you won't have to do a ton of processing.
I'd be more detailed, but I'm not familiar with Audacity other than using it to make wavs from vinyl.
Hope this helps.
