springs
shocks
struts/sway bar
Let's be honest here...because you have an Accord, it's pointless buy a CF hood for "weight reduction".

It'll make about 0.1% difference in the weight of the car.
Since you do realize that the car isn't going to fast in a straight line...that's the reason to work on the suspension. You can make the car fast in the corners much easier than making it fast in a straight line. And I don't know about you but I'd rather go have fun tearing up a backroad, etc than running a 17 second quarter mile.
And yes, springs and shocks/struts and swaybars would make the difference. Or instead of a spring/shock combo you could go with a coilover system like Tein, Apexi, etc. Springs like H&R and Eibach, Koni and Bilstien shocks. Sway bars...Eibach, or for a budget a rear TL-S bar by itself will make a nice difference for the money.
And sticky tires, preferably on a 16-18" wheel that can accomodate some wider sticky tires will make a big difference. Good tires alone on stock wheels will help immensely.
Don't do the suspension if you don't want to...but IMO there is much more value in investing in the suspension instead of trying to make it go fast via weight reduction with CF peices.
For a given amount of money you can make your car either:
A: Be a bit faster, but still slower most new cars, or
B: Handle better than 80-90% of new cars on the road.
If you like a soft cushy ride, then just leave the car alone, but if you want it to be more fun to drive and are willing to give up a bit of ride quality, do the suspension.
Do what you like, but it's good to have all the info to make your decisions.
