No, it's definitely not a Par30. The shape on those seem different. The bulb I'm pulling out matches a Br30 in shape, just about an inch, inch and a half shorter. I'm not sure I've seen a 65W Par30 either, and the bulbs I'm pulling out are definitely marked 65W.
As far as adjustability on the trim, I'm not sure. It looked like it could vary in length, but only with different trims. It didn't look like the current trim could be moved deeper.
I guess one thing I'm not completely sure is how deep the light should even sit. It looks a little far out with the longer bulb, but then the shorter bulb almost looks a little too short. (Although untill I ran into a different sized bulb I didn't really think it looked too deep). On the longer bulb, the curved edge of the bulb is about even with the bottom of the trim (the edge of the reflector coating is almost exactly at the bottom of the trim, although the installation on these could have been better, some seem to tilt a little show the coating shows). With the shorter bulb, the ****hest portuding curve of the bulb is just slightly lower than the trim. (I could probably manage pictures of the two different bulbs in the fixture if that would help).
My kitchen is getting pretty dark, I've now had 3 of the 4 bulbs there go out .
