Very nice table, 2 sites any vintage Thorens owner should register on are the Analog Department and the Vinyl Engine
the Vinyl Engine has any of the relevant owners, service manuals and mounting templates and the Analog Department has an excellent Thorens area, between the two of these sites you'll find every bit of info you need.
You're right about the tonearms the Mk I TP 16 is a heavier mass arm the other versions are lighter there are at least 3 of these versions.
I'd advise learning to adjust the suspension and get the cartridge set up siting and footing all squared away before you set about to add any damping and even then go light it's extremely easy to damp the life and dynamics right out of these decks.
