A belated welcome from another Subaru enthusiast (and Ambassador as of the day before I shipped off my Outback...) I'd imagine that you've already found subaruoutback.org, where there is a wealth of information. And there are various Subaru oriented Facebook Groups that might offer some options for you. (Subaru Outback Owners, Subaru Offroad!, North American Soft Roaders, etc.) I'm Rex Wagon on Facebook (Last summer I sold my 2002 wagon that I bought new) and "smorris" on most Subaru forums.
Here was my thread on prepping my Outback for our cross-country trip last fall:
