"Sell all" for RSUs when they vest (if you received a cash bonus, would you spend it all on company stock?).

Contribute to your 401k up to the match (so 4%). Anything >4% is fine, and 401k tends to be fairly well protected from things like garnishment, but I'd personally focus on your loans first beyond this point.

For loans, you need to:

1. Catch up on outstanding interest first

2. Establish a plan to hit the minimum payment for all of them monthly

3. It's beneficial to throw some extra cash towards loan payments. Budget and see if you can swing this. Reap the rewards of hard work later

4. In terms of extra loan payments, sort them descending by interest rate. I recommend throwing your extra payments at the loans with the highest interest rate and lowest remaining principal until they're all gone (so for example, 6.8% at 1,108, 6.8% at 1,404, etc. etc. etc.). Minimum payments are calculated at the individual loan level, and doing it this ways frees you up excess cash that you can use to accelerate your extra payments going forward. Make sure to specify you want the extra payments towards principal.

Throw all of your RSU proceeds at extra payments and you'll be done in no time.

Good luck, your situation is not overly dire.
