I have just a second tonight as other duties call but here goes...

PEPV1, the earlier editor for the 9600 was based on the NG editor and there were many similarities. PEPV2 is a .NET based editor package and was a complete redesign. You are forced to keep IR codes in the database, links no longer really exist (you have Common Macros in the latest version of PEPV2). Expect a learning curve with PEPV2. Use PEPV1 to import your PCF and get the IR codes converted into database codes for use with PEPV2. See the sticky threads about not removing PEPV1 posted by Peter D.

You can purchase high-powered IR emitters that will likely be able to control your equipment. The Pro RF-Extenders are wi-fi/network capable and no longer operate using direct RF. They use wi-fi. So, you will be replacing all your extenders as well.
