Any recommended frames for us shorter folks?
Like anything else mountain bike, pick a bike based on effective top tube length vs. seat tube size. Don't ever "downsize" a 29er bike thinking it will as nimble as your old 26'er. I would simply start looking at 17"+/- 1" frames. For smaller than this size, there have been the use of lesser rise stems, non-riser bars (still swept, however) and even the occasional flipped stem to get the handlebar height down. Really small frames also occasionally have issues with toe overlap.
However, I really don't think you will have any issue with a ~17" frame.
If I was going to buy a new bike today, I would strongly consider also getting one with a tapered QR15 fork, 2x10 drivetrain and maybe even a 142mm rear axle. Just about every manufacturer has a minimum of a hardtail and a FS bike. A large majority have frame-only available.
If you want to swap out your old stuff, you will obviously need a new fork, wheels and tires at a minimum. Since you are admittedly old school, modern frames have longer top tubes and often require a shorter stem than you might be currently using. Also, most modern frames have a fairly significantly tapered top tube for stand-over clearance. So, that 30" lilliputian inseam of your's shouldn't hold you back much!
