What if I went to an 11-28?
I'm worried about the 'spacing' between the gears because w/my current setup I already have difficulty finding the right gear at times to keep my cadence where I want it (I'm stuck choosing between a little too tall and a little too short).

I'd say its not worth the expense. Since you're not adding any more gears. Here's the gears in a 12-27 and the gears in an 11-28
12-27
12, 13, 14, 15, 16, 17, 19, 21, 24, 27
11-28
11, 12, 13, 14, 15, 17, 19, 21, 24, 28
They're basically identical and with regard to the end your concerned about, you're only getting one more tooth which is hardly a big difference (still noticeable though).
Shimano makes cassettes that go up 11-36 but you'd need to change shifters and the rear derailleur to accommodate them and even then I've heard its kind of a funky fix.
My suggestion is just get out there and ride. Practice spinning in your easiest gear to get up the hills and don't stand up if you can avoid it. Slide your butt back in the saddle a bit and focus on the full pedal stroke pushing and pulling up to maximize your efficiency. Standing activates the wrong muscles and will wear you out much faster. Also make sure you pedal through the top of the hill and don't coast until your momentum picks up on the other side. If you don't get to go down the other side then I wouldn't suggest going up it in the first place
