Both Bosch and RainX have part numbers on their respective websites and you can order them online. I needed them for a trip, so I was hunting around and eventually found the NeoForm wipers at CarQuest. So yes, I say so.
There are some aftermarket ones. RainX, Bosch and others make them now. I bought aftermarket ones from CarQuest, I forget the brand now though. Your best bet is to look up the product number from the manufacturer and buy them online. The local shops don't seem to carry them. Took me 6 shops...
A lot of us on here have gotten a custom tune from BlackBear (see my sig), and would recommend that. Alternatively you can buy handhelds such as superchips, edge evolution, diablosport predator, etc. Check www.autoanything.com, they have them there.
You need the Metra GMOS-LAN-02 or similar for the chime retention, and you need the PAC SWI-PS for the steering wheel. I've heard mixed reports on the compatibility of the steering wheel adapter, but I think it should work.
