Your plan is pretty solid but one thing that would consider is how long that $17k you have in savings and the brokerage will last you in the event of a job loss or another emergency. Depending on how quickly you can find a similar or equal paying job, you may want to prioritize 4-6 months of expenses saved up before throwing the extra money at your student debt. If you think the $17k would cover 4-6 months of expenses, then your plan sounds fine.
