Soooooooooo, got a buddy selling an IS300 with an LMS/LMW LS400 front brake conversion.
Hes willing to swap out my brakes, put them on his car, and put the big brakes on my car for $400 (everything and work).

Will I notice a reasonable difference? Is it common to do just the front?

Any point in doing the rears at some point?

He was able to do it with stock wheels and 15mm spacers. Got a short a short shifter tossed in. Very cool.

Im running stock suspension, but will be going to Bilstein struts. I am unclear on the RCA spacers, What are they for? Car is not lowered, and everything clears.

The RCA's are for clearance on the brake caliper, see this:


And the RCA's will actually lower the car, so if the RCA is 20mm thick - your car is lowered 20mm once they're installed. Read up on Figs site.

They clear with just the 15mm spacers - stock wheels.
