I have created a package that has two pre-deployment activities. 

The 1st is a bat file to disable the auto proxy config.

the 2nd is to uninstall the current proxy software. 

The questions come from the Uninstall Software activity.

It requires a Software Version. Since our machines may have different versions of the software that needs to be removed, can we use a wild card here?  IE: 2.10.* or 2.*  or just leave like 2.10.

For the Uninstall String, to suppress a reboot,  after selecting a predetermined string, can it be added to with the -NoReboot option? IE: $computername -NoReboot 

I've gone through the documentation, these topics aren't covered or offer very litle information.
