With your current equipment and setup (at least what you mention) I would recommend that you use your Pod X3 as the soundcard while recording - do not plug line in to your computer soundcard.
With the X3 connected to your computer via USB, make sure Audactiy is configured to use the X3 and its ASIO driver as the audio input/output device. Audacity has a terrible habit of defaulting to a pseudo-ASIO driver called Asio4All. Avoid it. It has been known to cause many problems with Line 6 devices because it is not a true ASIO driver. If you are/have been using Asio4All I think that might be the cause of your poor soiund quality (well, that and using your computer soundcard).
So... try another recording in Audacity making sure you are using the X3 and its ASIO driver. As long as you're doing that I don't think using Reaper will have a great impact on the sound quality. It has a great many more features, but that mostly has to do with how you can manipulate the recordings, and how many simultaneous tracks you can record. The quality of your recording is determined more by the hardware you use - in this case the X3 - than by the software.
