Having played bass for many years, you have a head start on any other drummer beginners. Sadly, like many things, there's no shortcut. Thwacking out a beat in your bedroom is easy enough. The hard part comes when its time to play along with other instruments, and on top of that, fills that purposely go out of time and come back in at the right place, half beats / off beats, rolls , paradiddles, beats other than 4/4 etc etc etc ( if you get that far )
Backing tracks would be a great way to kick ( sic ) off , so thats what i would do, and then just keep slogging, and when you've got comfortable with timing, start introducing a fill and come back in on time, and when thats going well, try other options like different timings, and synchopated rhythms that work brilliantly for funk
