A Denso reman (reman'd by Denso, not some other brand using a Denso core) is your safest plug-n-play bet. There are upgraded options that are a bit more work.

All of this.
For voltage testing apply max draw with lights, blowers radio your name it while running. Give it a little rpm. 1200 or higher If your alternator can't at least push 13.5 V it's time for a fix.
Load testing is the only real answer for the battery. You can get those specific gravity testers that are pretty handy and cheap though and test individual cells.
I'm not sure if these run a fusible link or not, but make sure there's continuity from the alternator output to the battery. Make sure the grounds are good too.
If you want to take a crack at fixing yourself, definitely use Tim's video. I have a local alternator shop that I use for everything car, tractor and truck. I've had good success with a NAPA premium stuff too. Never have put one on a Toyota though.
That is a real bummer if OEM is gone.
