On page 15 or so, in the section about "Creating an HTTP Profile" you will find great instructions on enabling an http-wan-optimized-compression-caching profile specific to SAP. That should help with compression.
The TCP profiles will also help if you haven't implemented that. That's detailed in the section immediately after the HTTP Profile.
In terms of RAM Cache, I would experiment with turning on the "Insert Age Header" attribute in the profile, Enabling Cache and then manually entering the URIs of the most frequently used javascripts. Make sure the date and time on your BIG-IP LTM are correct and pointed at an NTP server. Then, you can use a browser plug-in such as HTTPWatch for IE, to test the download and response times before and after the change. You're correct that this isn't in the deployment guide.
