AccuTracking

ok so i buy everything, and everything is working...what if someone shuts off the phone? and a week later i log into the site to track it, will it give it's last location?

It will give the last location the phone sent before it was turned off.

when the phone turns on again does the software start on power up?
TIA

This is configurable. The following KB articles may help:
