Welcome to Civic-EG, You got a really good deal on your Coupe.
The First mod I would recommend would be to lower your car. This will make it look much cooler as well as to help in the corners, After that a [u=http://www.civic-eg.com/viewtopic.php?t=10]Minime[/u] Swap. Basically putting a D16z6 or D16y8 SOHC VTEC head onto your engine, Thus giving you VTEC.
That Plus Basic Intake, Header and Exhaust(Refered to as I/H/E) will give you a quick peppy car.
For more ideas, Check out the DIY How To Thread, Its located under the "MISC" pull down window on the top of every Civic-eg Page.
