There's a lot of things on YouTube under "drum lessons" (I know, duh).
A teacher I had said playing a musical instrument started out like falling in love. You become infatuated/fascinated with the instrument. When I was about 9 or 10 I always watched drummers and looked for drums in stores. That's the first step and it never goes away.
The next step is fooling around by yourself. He said to do that for 1 -2 years.
The next step is getting accurate knowledge. You can do that by the "look under every stone method": private lessons, listening to recordings, on line videos, watching good drummers, talking to drummers etc...
None of the steps goes away, the next is just added on.
It sounds like you're in the second stage approaching the third, so I think the best thing you could do is what you're doing - fooling around, playing with some songs and checking out YouTube etc...
some basics:
all drumming is based on the single stroke roll (R-L-R-L) so practice that, and make your kick do 1/4 notes with your hands doing 1/8ths' or 1/16ths.
your hands won't be solid if your feet aren't, so feet first.
you're an accompanist, so try to get to the point where you can put your drumming on autopilot and listen mostly to whatever the lead thing is - the lead vocals or guitar solo, whatever the hood ornament is at the time.
I know a pro drummer here and if I phone him up and tell him about a drum I just got you'd think you were talking to a 10 year old, the excitement never went away and he's in his 50's.
