Factory air if you can find brackets to hold the compressor, I am betting they are rare. Same for the power steering, they come up on e-bay every now and again.

Automatic with overdrive, 200R4 or 700R4 will bolt right up, will it have enough power to pull it in overdrive? maybe, maybe not, depends on the weight of the truck and how hard you wish to push it. My '37 weighs in at 3300 with me and runs 70 mph all day long at 2300 rpm. Not sure it would do that with overdrive, it doesn't have much torque below 2000 rpm (stock 250 with two one barrel carbs). Fuel milage in the 15 to 17 range depending on the wind and speeds I drive.

Floor shift, sure Lokar sells quite a few of them and they are nice, easy to set up and install, and work great.

Chrome is out there buts its all cheap import stuff and hard to seal. I switched back to stock parts, got tired of the leaks.

Performance parts, some but not like a small block, cams mostly. A easy up grade is 307 V8 true flat top piston, direct bolt in and will raise the compression about 1 point, some where in the 9.0 to 1 range. All 230, 250, 292 heads are the same with very slight differences in compression, nothing to shop for. The early 194 head will raise the compression more, but the ports are terrible and require some work just to work as good as a stock later head. Jump over to www. Inliners.org for more performance questions and links to high performance parts.
