2. New TV with 4K/HDR/WCG and best black levels and contrast ratio I can afford and fit. Likely 50 or 55 inches, OLED or FALD LED-LCD. My Samsung LED-LCD from 2013 is lacking these new features and really limited in blacks and contrast ratio. But it has a great picture in most other aspects of PQ.
3. 2nd sub and/or Atmos modules for fronts. Possibly get Prime Sats to match my Prime Bookshelves and center fronts. Currently using Cambridge S20 sats as surrounds and not sure if Prime sats will be a worthwhile upgrade.
I am still figuring out whether I need a 2nd sub for just the MLP, since EQ is highly effective. However, it would be nice to not need it as much and not have the back wall, especially back left corner be so excessively boomy and loud, especially around 42Hz. Current EQ works pretty well in MLP and middle of room. It's the back wall that is downright unpleasant.
My current HT setup is Prime bookshelf and center fronts and Cambridge S20 surrounds with a Samsung 46 inch UN46EH6030 LED-LCD and Yamaha HTR-3066 5.1ch AVR. My sources are PS4, XB1, and X1 cable box. I use my setup mainly for movies and games and some casual music listening in the background when playing driving games or working out. It's also a bedroom so the MLP is on the bed, which is along the right wall. I have chronic back pain that limits me to the bed as a MLP as I cannot sit or stand for long enough to watch movies.
First off, your measurements look pretty darn good, nice job on that. Judging by that, adding a second sub is likely only going to give you more output, not better quality. It looks like you don't have any serious nodes, just some small dips. During high LFE scenes, though, having two subs makes the whole experience feel more realistic, so there is definitely going to be a plus, I just don't think it's an immediate need.
Since you have to lay against that back wall, I would highly recommend some kind of treatment behind you. It's really the only way you're going to be able to fight that bass boom unless you can move your bed back from the wall and use a headboard. The more material you can get behind you and in the corners to the left and right of you, the more you can treat that boomyness. Four inches of fiberglass absorption panels/bass traps is ideal.
I would honestly consider some room treatments long before I'd consider upgrading your satellite speakers or even adding a second sub. Treatments will give you far more benefit, especially in a more even and wider soundstage, less boomyness in the bass, and better bass and even vocal articulation. I would look at GIK, ATS, Acoustimac, and NextAcoustics if you are cool with foam and not heavier fiberglass style panels. Vicoustic also makes great foam stuff, but they are under a dealer model so it's expensive.
If you aren't able to treat behind your head at all, at least get corner bass traps and hang at least a 2" panel on the wall above your head.
