Just take it slow Glen. Have lots of clear clean space to lay things out on. Take lots of pics as you go.
I have no particular engineering/mechanical experience, but found the exercise extremely helpful to better understand the weaknesses in the design and see what all the adjustment options are. Getting rid of the transfer gears has got to be a help. Nice to have quiet purring during slews, rather than grinding punctuating the start and end of each movement as it was pre-mod.
Key things to watch in assembly include tension on worm bearings, worm/gear adjustments making sure to keep rotating by DEC and RA as much as possible (there will be some parts of the worm tighter than others). Follow the tips on getting the belts on, putting bit of plastic over allen keys etc.
Astrobaby has a good guide on EQ mounts too, and Peter's previously linked page has lots of great background to get you in the zone and build confidence.
