Don't overlook things like tyres as well. A lot of the Honda guys I know use Toyos, but I'm a Falken man. Bucket seats will make a huge difference as well (unless you're the size of Shaq). You could get these from the Type R.
If you're stuck for upgrades and don't want to spend too much then looking at the Type R is a good idea. Especially with the brakes.
Hopefully that's a good read and if you have any more questions then feel free. I used to love Hondas before I converted BMW!
Now, the part that will make the car fun is the suspension. Coilovers are an easy way to get the car decked and handling well (Skunk2 and Tein are good options but expensive). Thicker anti-roll bars (ARBs) will stop the car rolling so much in the corners and polyurethene bushes (poly bushes) will stiffen up the chassis. Be aware that this will make quite a stiff ride and isn't suited to everyone. I have this sort of setup on my BMW and pot holes and bumps are no fun! But, when you get yourself onto a really good, smooth, winding road nothing can keep up!
Brakes will need to be upgraded as well. Braided lines and better pads are a good start. Before moving onto bigger discs and calipers.
First and foremost and engine swap would yield the best pound for pound power increase, but if you're against it that much then you can make up for it with your suspension setup.
AEM make good CAIs (Cold Air Intakes)/ Induction kits. There are so many exhausts available. The key here is the diameter and design. I had a Greddy system on my old Civic. I would say no bigger than 2 1/4 inches diameter. I would go with a 4-1 design on the manifold. The other option is 4-2-1. 4-1 is better for cars that make all their power high up in the rev range (just like Hondas). 4-2-1 is better suited to low down torque. I think Skunk2 and DC Sports make them for your car.
