If you dont plan to do engine swap anytime soon, best mods I would go for is an air intake. Short ram intake will give you a 7+ HP boost or if you want to go with Cold Air Intake that will give you about a 10+ HP boost and will make your car sound really nice. Also, get an exhaust system. That will give you about 25+ HP boost or more depending on the brand you get.Automatic transmission and modding or tuning do not go in well but in this situation, if you want more handling, go with springs. But if you have the money, go with coilover suspension making the car take the turns real tight and give you excellent handling. Other options would be strut and sway bars. They keep the car in place and making it stiff so it wont go crazy. Excellent option for handling also. And last but not least, rims and tires. Rims are lighter than the stock honda rims you have and tires will increase grip on the road for better handling as well.I hope this info helped and godspeed.
