I am trying to compress a bluray into a 1.45 GB MKV file.

Never done anything with AVC before so i tried Handbrake. The file looks pretty good. I'm just wondering if there are any settings i could try to make it the best it can be.

Here's the media info of the result.

Code:

Those settings are already reasonable. If you want to increase quality further you can invest more time and use one of the slower presets.

AFAIK: yes.
If you scroll a bit down you will also find tunings on that page. (choose film for typical movies, like Hollywood etc.)

Well, if you are doing it for archival reasons, might as well do it once and do it good right?

Personally, for Q/TGMC encodes that I really like, I use CRF 18 and Placebo. It takes 2 days on my Core i5-450 laptop, but it's worth it.
