I bought vintage Shamals...Now what?

[in_version]

Long story short, I want to build this bike:


Through a lot of magic and ebay and craigslist and iphones, I am almost there. I found an incredible deal on a set of shamals, and although they are in good condition, the tension is all over the scale. The thought of riding these is a bit scary to me as I am about 185 lb and ride fairly aggressively, and I have never ridden wheels with less than 32 spokes.

Hoping I can receive some input.
Has anyone ever broken a spoke riding these?
Anyone ever rebuilt them? (Paging Dr. Spud)
Thoughts on replacement spokes?
Cleaning brake track?

A few spoke holes are beginning to look like this:

9 speed on the old style hubs, was this a conversion? Also notice the DT spoke used as a replacement.
