Stick with the Honda Factory Wipers. Everything aftermarket sucks and will streak, skip or squeal within months. You can easily get a year out of factory wiper inserts, and they're $10 ea.
Air Filter / Cabin Filters are super easy, and aftermarket ones work just fine. I prefer the charcoal activated Cabin Filters
The key fob you linked is $170 and you will have to take it to the dealer and spend probably 1/2hr to 1hr labor (depending on dealer) to have it programmed and risk paying the programming fee and not having the fob work, or be compatible and then pay the fee again once you get a new/different one. I highly suggest you don't mess with internet keys. We have customers bring in online keys all the time and half the time they will not program, and you're on the hook for the technicians time. $300 is not a bad deal if it includes the programming.
