Deere 1795 planter maintenance.

I’ve got a 5 year old 1795 16/31 planter. It’s got about 10,000 acres on the corn rows, so I’m sure I’m due for a rebuild.

Question: What parts should I be looking to replace? Openers for sure, scrapers? Press wheel bushings? OEM vs aftermarket? I’d like to get my list together. Thanks all!
