well the ls motor..along with every single honda motor out there (atleast it seems like it) lacks torque. The LS motor is a good base engine wiht 140hp at the fly and u can get a lot done with it but a GSR swap would be a plus! Suspension wise I have h&R sports on my car which is a 1.5 front and 1.75 back drop and I think its perfect. $156 off tirerack is a great price i think. The Eibach sportlines on the other hand will lower your car about .25 inches more than the sports but you pay $100 more. So i would definatly recommend the sports.
www.tirerack.com is where i ordered mine
