Hey Dan,

Welcome to the wonderful world of Hondas. Where everything interchanges just like the older bow-ties.

Seat options you have are.
99-00 Civic Si seats. They are like bricks and don't hold you in. Plus you have to change the rails, no big issue very easy todo.
94-97 DelSol seats. Very low to the ground and IMO very comfy. Some may say they are ugly like many of my ex's.
94-01 Integra seats. Bolt right in. Stay away from Type R seats as they are very pricey and for what you want...are useless.

Center console options are : JDM center console.
Cupholders in hondas are stupid anyways. They won't hold a REAL drink. Get a armrest from a 92-95 four door and put your large coke in that, haha.

Anymore questions, don't be afraid to ask.
