Welcome to the forum!
Congratulations on the Sparks.
Sea Doo sells two different solutions to your docking problems. I can't verify how well they work because I just use pool noodles when I have them at a dock. They offer snap-in fenders:

And side protectors

As far as cleaning goes, I just wash my Spark with soap and water.
I'm 5'11", 185lbs and have 24 hours on my Spark. The seat looks just like it did when brand new. I would consider taking your worn seat to the dealer and see if they will replace it under warranty. You wouldn't happen to have pictures of the worn seat that you can post?
