Hard to say with any certainty without seeing the fuller picture, but some high level thoughts:
If your current salary is high enough then Traditional IRA and 401(k) and HSA are good. For me, it is a no brainer at 25% bracket, and a 'perhaps' at 15% bracket. I would personally contribute to the HSA in full before looking to fill the IRA bucket, assuming you've got a solid amount in 401(k) and IRAs already.
You should double check on the pension, ERISA gives 5yr cliffs or 3-7 stepped, 10 is non ERISA, which can exist, but are rarer. I'd make sure you don't qualify for something at 5yrs or so before you quit.
I would not keep an emergency fund now, I would put that into the IRA, using a Roth for the emergency fund. If you get serious about school, then you can save an amount to cover that, but that isn't an 'emergency fund'.
