Hello,
If you recorded on a track, you should see a wave form for that track. Before recording you have to enable that track for recording then click record above and play to start recording. Also usually on the fastrack you have an input for a mic and one for guitar. On the track for the vocals you have to select the input 1 for the mic and 2 for the guitar track. You can search YouTube for videos on SE that may help.
As far as playback from speakers, if you don't connect your headphones to the fastrack the sound should come out of your speakers connected to your computer. If you don't want to use your computer speakers disconnect them and You can connect studio monitor speakers such as M-Audio Studiophile 30v to your fastrack RCA outputs.
Hope this helps,
