I"ve noticed that ATC is always very interested in which runway
you will use when you call for your release. In fact, I believe my
clearances have always included the use of a certain runway (after they
first ask me which one I want). Does that assume I won't do a 180 after
take off???

Depends on the airspace. If it's really busy and you pick runway 35
then your clearance will be tailored for that runway and probably
wouldn't work off rwy 17 for example. If you tell us a runway that you
will use ATC can then issue a clearance that requires the use of that
runway.
