RD's Electrical Adventure Mods - Part 1 - The Prep — Modification Questions

Figured I needed a place to capture the next few weeks of mods as I'm a total electrical noob and I'll be needing some help along the way.

Got the bike in late Feb and so far I've completed:

Signal Dynamics Wig Wag brake light modulator
Signal Dynamics headlight modulator with new Silverstars
Rim Wrap - silver rim tape (decided against the yellow)
NEP Cruise control
Fenderectomy with cool LED license plate light
Grip Puppies grip covers (coming off for heated grips install)
Started tankslapper install with tank protector strip only

Hopefully, I'll get the mirror extenders shortly and finish the tankslapper install on the next warm weekend. Still waiting on the Chinese levers. Since it's going to be rainy for the next week or two, thought I'd get to the electrical stuff. On tap:

Symtec heated grips with round toggle switch
VFRNess with accessory bundle 3 switched, 1 unswitched
Stebel Nautilus horn with wiring kit
Lascar EMV1200 Voltmeter (think I want to paint the bezel black too)

Any thoughts on the order of the mods?

I was thinking:

VFRNess - obviously
Lascar - to be able to read the gauge as I do the others
Symtec - same mounting location as Lascar (left black panel under clutch - must dremel/drill panel) http://www.vfrdiscus...-photos-010jpg/
Stebel - seems the biggest pain depending on mounting location and can ride without it if I get frustrated.

Can this be done in a weekend and still have time for a set of tennis and church on Sunday?
