what to do next?

Ok, I finally got the I/H/E and the spark plug into my 95 CIVIC 4D AT...and now I dont know what to do next for my engine to boost up the HP. I was planning on getting the AEM CAM GEARS, but do they made for AT. If not, wat else can I do to boost up the HP? And I have another question, I saw that a lot of cars have really soft steering wheel, and my CIVIC's steering wheel is kinda hard when I turn. Do you guys know what I am talking about? Any ideas would be really appreciate.
