My '11 has the torque converter drain plug, and yours should too. Just turn the crank bolt to get the plug to show, then pull it out to drain.
Replace the filter of course, and clean the magnets in the pan. Be VERY careful not to get anything like even lint inside the trans.
Once back together you will need to fill with the blue fluid thru the bottom, start the car, shift thru the gears, fill some more, then run the car until the trans pan reads 80 degrees C, and drain until it dribbles.
Not that difficult, just time consuming.

I would say leave them alone until they are a problem. It may only affect 5-10% of all 7 speed cars, so we may go a lifetime without a problem, or it could happen tomorrow.
I believe the 722.9 trans requires 'marrying' the conductor plate to the trans with an SDS, which only a dealer can do, so there is no sense messing with the CP.
I think the speed sensor can be changed without SDS, but don't quote me.

+1 on the conductor plate issue. Dealer work only. Dont even worry about it unless you start experience erratic or jolty upshift/downshifts. I dont think I've even heard of that issue on the later models 722.9 with the torque converter. Mostly just with the earlier 7 speeds when they first came out
