It's only the two titles at 0:42-0:45 that have the mask/roto. All the others are simply timed well to the movement. So you can achieve 90% of the look with practically no work.

Check out dxomark.com for optical quality measurements.
If you want 1920x1080 I'd recommend no less than 1066x. 1920x818: 1000x
Komputerbay are the ones to buy (low price), but they vary a lot so test them while you can still return them.
The answer depends a lot on whether you're matching to other footage, but if it's just the S Log from your sony then there are a couple ways:
The simplest way would be to use any FC (Film Contrast) LUT you want first, then tweak it a bit after to make sure it's properly exposed.
A more complex way would be to use the FP (Film Print) to start and then go crazy with your own creative grade on top of that.
The most "involved" way to use them would be start with your choice of film stock FP LUT, do a heavy creative grade on top of that, and then finish off with a film NEG FC. This process is the closest to how shooting 35mm film works today where the camera has a film stock, which is scanned and graded digitally, then distributed on a film negative for theaters (Digital projectors are starting to eliminate the last step).
Personally, I rarely go the last route because Impulz LUTs introduce a lot of color noise so I usually start with a FP or FC (with the strength around 50%) and do a heavy grade over that. Eliminates the need for noise reduction for most shots and gets the basic benefits of subtle film-like color shifts and a film-like contrast curve.
(You will probably never use CIN unless matching with footage that was actually shot on film.)
You've got a camera from the future?? JK. Given what you're considering already, I'd say look at the Sigma 18-35mm 1.8 Art. You'll need an adaptor but it's probably worth it.
But between the two you mentioned, I'd probably get the Sony 35 unless you need a cine lens for pulling focus or changing iris during a shot.
Just FYI Rokinons are pretty good, though!
keh.com is reliable.
Borrow Lenses sells used gear too (but I'd probably stay away from lenses with IS from them because of all the vibration from constant shipping they've endured).
