Re moving audio to playlists, its pretty simple. There are likely a few ways to get the desired result, so here's my method:
1-create as many new(and blank) playlists as you have track/audio to move.
2-(one at a time)highlight each additional audio clip and hit COPY, then:
3-use the p or ; keys to move the cursor up or down to an empty playlist and hit PASTE(doing it this way will keep everything in the exact same timeline position)
4-when you have copied all your audio, you have options on what to do with the original tracks(see *** below)
In case you're wondering why I say COPY instead of CUT, its simply a safety measure.
*** what you do with the duplicates is up to you, and how much drive space you have. To be safe, I would use the Hide and Make Inactive option(so you delete nothing, but clean up your screen space so all the extra stuff is hidden, and uses no system resources. Otherwise, you can simply delete the original tracks(because you are new to this stuff, I would play it safe)
