I am fairly new too, but every recent reference I have found, and advice given to me was simple green as a cleaning solvent.  I used plastic tubs, large enough to fit the sub assemblies, to thoroughly drench them in simple green with a spray bottle (except the motor) and scrubbed gently with an ultra soft bristle toothbrush.  This worked very well, simple green appears to be very effective.  It did take a bit of detail work with the brush but the varnished oils did come off with gentle scrubbing.  I rinsed with water and dried in the sun with a fan on it.  I used light oil like one would do on a firearm, light coat over the surfaces.  I used a small paint brush as an applicator.  Teletype Model 28 Gets a Bath – Stickelman.net

In the ball bearings, I found the old grease polymerized and it behaved like wax.  I used a rigid plastic pick (Rothco Gun Cleaning Pick & Brush Set) to remove the old grease and replaced with grease from NAPA - Super Lube Silicone Dielectric Grease - 3 oz NCB 91003 | Buy Online - NAPA Auto Parts.  I had to disassemble my motor to get to the bearings in it since it squealed from time to time.  Getting the waxy old grease out stopped the squealing.  Not sure if the 35 motor has ball bearings in it, but it looks similarish to the motor like in my Model 28.

There are a few interfaces out there that you could use, but I ended up with the deramp model.  I am waiting on a DB9 to RJ11 to complete that setup, but it looks like deramp makes a Model 33 interface - Teletype RS-232 Adapter that may work on yours.

1. Although it looks to be relatively clean and well oiled, the seller
advised me to clean and oil it first.  What is the recommended procedure
for this?  I am assuming that each sub-assembly (printer, tape punch,
etc.) should be removed and processed.  What solvent is best, and should
it be dunked, sprayed, or what?  What lubricants should I use?  I was
thinking of just spraying it with Starrett M1 oil.  Would this be
totally wrong?   Every Teletype I've ever seen looked like the insides
had been given an oil bath.
