Tim -
The questions are really pretty straight-forward.
1. What is the nature of the employment - full-time, W-2 or 1099. Depending on the industry, they may have other terms for these, these are the terms in IT I am familiar with.
2. If full-time, no worries. Doubtful, since this is an agency though.
If W-2, ask about access to benefits (esp. important in MA). Next up is the cost of said benefits, they should have a rate schedule for you to look at or keep. As I mentioned, some companies do not offer any W-2 benefits, they only take on the taxation responsibilities. If it' a MA agency, they should understand the interest in benes.
If 1099, basically you need to know about any additional requirements the agency has for 1099 employees, such as the insurance I noted. And, I would still sit with an accountant for an hour, esp. in Taxachusetts, to make sure you have all of the employment tax angles covered. Not needed if you're W-2 as the agency takes all of that on.
If they offer an option, ask about the rate difference between W-2 and 1099. Typically, it's about 10% in IT, YMMV.
Do not ask about the rate they are getting for your services. They won't tell you and it will annoy them.
