That answers your question about snowy picture. Quit using the modulator to broadcast and stick with a direct connection until your TV works normally.
As to which picture quality adjustment to do first . . . don't waste time on any of the color adjustments until you have a flawless black and white picture. No horizontal or vertical jitters or bending, no problems with vertical and horizontal linearity, and so on. Going back to mess with those things after you have spent hours on color adjustments may force you to do the color adjustments all over again.
The multi-step procedure for color adjustments is described in pages 28-38 of the RCA factory service manual:

You begin with purity. After that, you set the grayscale using the screen and background controls (the manual calls this "kinescope color temperature adjustment"), and so on. Do these procedures in the order laid out in the manual, and if you can't get the right result at any point, stop and find out why.
BEFORE doing all of that, you might want to look very carefully at your picture to judge whether those procedures are needed. It's quite difficult to get perfect convergence around the far edges (top, bottom, sides) of a roundie color picture. If yours already looks good, you might want to let sleeping dogs lie. Look for color fringing in the edge zones -- that's a sign of less than perfect convergence. If your TV looks nice and watchable already, maybe it doesn't need twiddling.
