Glad to hear you're jumping back in!
Do check out
Kenny Gioia's excellent Reaper tutorials, he's the deFacto standard for Reaper instructional videos.
I'm a long-time Reaper user and am using it for video editing, also.
If you happen to be in the market for small monitors I recently bought a pair of the
Presonus Eris 3.5s. They are great as small personal monitors but they also are currently shipping with a free download of Presonus's Studio One DAW which many seem to like a bunch.
