Does reversing lower the quality?

Reversing itself is lossless — it only changes the order of the samples. Choose WAV or FLAC for a bit-perfect result, or 192 kbps or higher if you want MP3.

How do I reverse only part of a file?

Cut the part you need with the Audio Trimmer first and reverse that, or reverse the whole file and trim it afterwards.
