Does anyone have a DIY checklist for the 15k service?

What's the OEM part for the air filter that is due for a change?

What will a shop do for inspecting the hoses that I can't do up on ramps?

All maintenance schedules are in your owner's manual. If you don't have that, check here: 2011 Subaru maintenance schedule and new car break-in period

Essentially, at 15K all one needs to do is check fluid levels, change the engine oil, and change the cabin air filter. The cabin air filter is behind the glove box. There's a writeup for changing it in this forum.
