^ this. lol
I had a 08 CSX up until just recently... it was a lease so I left it completely stock. That and it didn't really have the performance I wanted. Why I got it is a long story that I'll skip. I now have a 08 Civic SI sedan so I'm still up to date on the Civic performance stuff.
For starters... one of the first things you're going to want to get is a rear sway bar. You can either get the one from the Civic SI sedan... or you can get one from any number of companies that make them for the 06-10 Civic. Progress, Blox, Eibach etc etc. It will help to give you a little more roll control and some more feedback. Combine this with lowering, a set of sticky tires and you've pretty much completed everything you want for a daily driver. I wouldn't give yourself delusions of grandeur with this car being a track toy... it's really not going to do it unless you gut the interior and change up your seat. :P
Anyway... if I were you, I would look into ST Suspensions Speedtech coilovers. ST Suspensions (formerly known as Suspension Techniques) was bought out by KW and is being used as their entry level coilover system (not a bad thing). The Speedtechs are identical to the KW V1's except for the fact that they're made from galvanized steel instead of stainless like the V1's. We don't get all that much salt here so I wouldn't be too worried about stainless vs galvanized. The other benefit that ST/KW has is that the spring seats are composite so they won't seize to the threads and screw you over after a winter when you want to change ride height.

They go for $895 CDN I think... very reasonable for KW quality. The ride is pretty good, so I wouldn't even worry about adjustability unless you plan on hardcore tracking the car. A lot of people are so caught up in being able to set stuff but then never end up touching it again. The ride is similar to stock, firmer without being really bouncy.
Make sure you get camber arms for the rear, camber bolts for the front and get an alignment.
For wheels you can go about as wide as 17x9 and don't need to roll or pull your fenders (dependent on your choice of wheel), unless you want the super slammed, "hella flush" look.
Buy your air/oil filters from Honda instead of Acura (if you want OEM stuff)... you'll save yourself money for the same part.
