Year: 1984
Make: Volkswagen
Model: Jetta
Engine Size: 1.6 TD
Refrigerant Type: R134a

I've got my system charged and working with R134, I'm now attending to some details and trying to clean a few things up.

My suction lines originally were wrapped in insulation which was moldy and fell apart.

I've bought some of this Frost King 1/2" rubber pipe insulation at Lowe's:
Frost King Rubber Pipe Insulation

The ID of this is 5/8" which is perfect. I have not fitted it yet but think it will work well, unless someone has something to say against it.

Also, the original AC setup had some sort of putty/clay type thing around the evaporator capillary tube and general connection points. Here is a photo:

What should I use to replace it? Plumbers putty? Something AC specific?

What you need for the TXV & that short metal suction line is called Presstite tape. There really is no hardware store equal, it is pretty MVAC specific.

You can buy it HERE.

The rubber insulation is just fine to replace the rotted foam on the OEM lines. Make sure you secure it well if it is the split tube.
