Can't really comment in much detail because no one here knows what your videos look like. Can't help with x264 command line.

Depends on the final disposition you plan for your encodes. I assume the colorspace and deinterlacing are for PC-only or web display, although you likely can't use i422 for the web. The better computer media players are good at deinterlacing, but maybe you're not using one of those for PC playback. Are you sure these VHS sources are interlaced and not telecined? VHS recordings of movies and animation usually use some form of pulldown (telecine). Obviously you don't intend to go to DVD or BluRay/AVCHD for these videos -- the frame size, colorspace, deinterlacing, and frame rate would all be out of spec for those formats.
You might consider these points:
QTGMC(Preset="Slow") and QTGMC() mean the same thing. "Slow" is the default. Are you sure you need the strong filtering in slow mode? Faster modes filter less, run faster, lose less detail but still do a decent job of cleaning.
Why are you cropping? Bad borders? Head-switching noise? Anyway, thre's always a quality cost to resizing, especially when it's not necessary, and especially if it alters the original aspect ratio proportions of the image. We have no video sample, so no one knows the original captured frame size. Resizing involves greater rounding errors when resizing by small fractional increments like 0.2x instead of 2x, 3x, etc. Resizing can be avoided by replacing cropped portions with AddBorders() to maintain the original image size + proportions.
