I've "rolled" a couple 401ks into a Vanguard account. Just set up a Vanguard traditional IRA (or Fidelity is good too) and follow their instructions. In both my cases my old 401k admin sent me a check and I forwarded it to Vanguard within a certain time frame. If you don't know what fund to choose just pick "Vanguard Target Retirement XX" for whatever year you turn retirement age (Fidelity has equivalents).
The reason I say Vanguard or Fidelity is because they have rock bottom fees and also they are huge so they've worked this out with basically everyone.

Fidelity is good, but Vanguard has lower fees. Stick in all in their S&P 500 index.
