You just need a good gauge wire from the battery to a relay, and out to the pump. Followed by a good heavy gauge ground wire.
You can trigger the relay with the stock FP's voltage feed wire (Gray)
Probably $15-20 worth of stuff from your local ACE hardware

the "branded" kits vary from simply some wires, connectors and relay thrown in a box, to a complete click in each connector setup.
personally i find them all to be overpriced, but they have to make money, and im just used to doing it myself.
yes.. and in my opinion, if you have a large enough fuel demand to warrant a upgraded pump, its worth it to upgrade the wiring to the pump... the wiring alone will show a decent gain.
most cars have between 10 to 11 volts at the pump... remember the cars electrical system isn't 12v.. its supposed to be between 13.5 and 14...

As for making the hotwire kit, what i the general idea / methodology?
take 10 gauge wire from the terminal on the alternator and fuse it then run it to the relay? Have the relay controled via the original fuel pump power wire?
Im just wondering if it would pay to trace all the original wiring and use the stock relay and fuse holder, but with larger gauge wiring.

what do you mean? Both pumps in the tank are going to be run by the same wire entering the pump assembly anyway. How do you have the 2 pumps wired to the connector?

general idea is theres a voltage drop from the smaller stock wiring..
so a nice thick gauge wire goes from the back of the alternator to a relay at the rear of the car (put a fuse inline up front..)
relay is kicked on by either the orignal fuel pump power wire, or the stock relays turn on wire... most people use the stock fuel pump power wire because its already there.
its possible to reuse the stock relay to do it, but ive never done it that way.

I have a 10 gauge wire runing to each in-tank pump, I use seperate wires since I have one pump running off a hobbs switch for street driving. I have a racetronix hotwire kit on one pump (had it on there for a while) and I put a new relay up front for the second pump. Put the relay up front since it was easier to get the hobbs switch close to it.
All you need is a relay, connectors and some wire, I suggest soldering everything since fuel is somewhat important
