Re: Tele pickup tapping
Ahem... I can answer that. It will work perfectly with it. Keep the same 250k pots. Do experiment with your caps, .011, .015, .022, .033 work best, I like the cheapest assed caps I can find. The sound will be a little rough and inconsistent at first, but will mellow out after a while.
I have never tried a quarter or hot for tele, but I have bridge rails in a tele, and it's awesome. You get humbucker output and sound, then use the split of you want (I don't use the split much). The sound balances out well with the stock neck pup, no issues. My rails are not Duncan, I believe they're Alnico V. Duncan rails are ceramic. Nothing wrong with Ceramic.
You may have to reverse the bridge pup hot and ground, the wiring around for some (maybe yours) neck pickups may be necessary. If it sounds wimpy or thin, try reversing the hot and ground on the bridge pickup... or use the "reverse phasing" instructions on the diagram.
Here is the wiring diagram for the quarter pound, it details the coil tap wiring, and mentions the switch at the bottom:

Use the hot rails for tele wiring diagram, and substitute the mini switch for the push-pull. Drill a small hole in your control plate between the Vol and Tone knobs and mount it there.
Use a mini toggle switch. Oh yeah, the rails have everything a regular tele pup has, but then you gain the ability to play hard rock and a little metal on it. Also, you can bend without losing the note, a big big plus, I like to bend on leads. single coils just always lose it on big bends, and with rails it's never an issue. That's the main reason I love rails. You only gain, lose nothing.. Good Luck!
Here's me tele, a Peavey, good as any Fender, with the rails it kicks ass:
