rdlgrega,
I guess the ones who produce the gold valve would be the best source for set up.
We sell the MX-TECH Works piston in kit form along with set up info. The only way to correctly service a WP shock without a circulation pump or vacuum pump would be to build the entire shock under fluid, interestingly enough, we have customers who actually do this.
The bladder(ughh) or schrader valve deal will allow you to servic/build the WP shock without the correct tooling, but you'll still have air in the shock unless you build it in one of the three above mentioned scenerios.
Take Care,
