Aggro,
First off welcome to the forums and OOTP.
As far as your Q's:

1) The easiest way to move around quickly is use the "Recent" drop screen on the top right hand side of the screen. Not exactly what you meant but hopefully that helps.

2) You can DL your game onto 3 different computers actually. However, you can DL it as many times as you want onto those three computers.

3) Scouting is a crap shot. I have heard some swear by it....and, others just curse it. I fly by the seat of my pants and never use scouts. I usually fire them all from top to bottom and never hire anymore.
Depnds on what you wanna do I guess far as scouts are concerned. They will once and while they will find a gem. Although, IMO it's not worth the hassles.

Hope I was of help and once again WELCOME!
