According to:
American Wire Gauge table and AWG Electrical Current Load Limits, 26 AWG wire is good up to 2A... We're using about .5A so you should be good there.
They do sell phone line extension cords, but they're not that inexpensive... probably around $8-10 at RatShack. What were you planning on if you weren't going to add a jack? Or were you just going to use phone wire because that's what you had handy, and just wire directly from the board to your car? That would work OK, but would require cutting/splicing if you ever needed to pull it out for updates or repair.
If you have one of those computer hard drive splitter cables, that has a male and female molex connector that you can cut off, and 4 pins each. A nice quick disconnect. Those are only like $3-4 at radio shack and you could splice whatever wire you want to hook everything up.
Lengthwise on the cable really depends on your car, where you're going to tap everything, and where you're going to mount the 'guino. Unless everything is near to eachother, I would recommend using separate cables at least for power/gnd and injector/VSS. This is what I did - power/gnd is a twisted pair of 18AWG to the battery, and injector/VSS is another length to the ECU. They're both in different directions from my 'guino so a 4-conductor cable wouldn't have worked out.
