As far as the upscaling to anamorphic is concerned you should definatly check out a small tool called "Video Enhancer" (www.thedeemon.com), it's the only resizing/upscaling method I know of that is temporal-based and gets detail and sharpness off the neighbouring frames. I've tried various upscaling algorithms (Lanczos, SSpline, RedGiant's InstantHD), and they all do pretty well but the "SuperResolution" does more than noticibly better. 30$ well spent for me. There's a version for AfterEffects available too, but it costs a 100.
I can think of a couple other temporal based sharpness filters, the best of which is currently used in my GOUT stabilization script. ;) I think it is important to temper people's expectations about "super-resolution". Super-resolution only works for things that are moving. This is a good thing for sources that suffer from DVNR smearing such as the GOUT, but for sources without smearing, all you're doing is getting rid of motion blur. Since all of the motion blur on the Pre-THX LDs is intentional, this would probably not be a good thing.
The best upsizers actually use Edge-Directed Interpolation. Arnie.d has already indicated that he plans on using NNEDI (Neural-Network Edge-Directed Interpolation) so I think he's already heading in the right direction.
