I am employed privately and I also receive payment for service in my city as a planning commission (about $50 per meeting...so...yeah...rolling in the dough). Anyways, my service on the planning commission also allows me to utilize a 457 plan. So here is my question, what should my retirement investment priorities be? Are the below thoughts correct?

Here is my current priority list:
1. HSA - Invest enough to cover the yearly deductible. Replenish up to deductible level as needed each year. If there is enough, don't keep investing until priorities 2-4 are maxed.
2. Roth IRA - Invest to max
3. 457
4. 401k
5. Finish off HSA

I don't think I will make enough money to max these out, but I can probably get 1 & 2 and part of 3 with occasional years where I can do more. Am I prioritizing these correctly?

Thanks CB
