Need ideas for 02 Accord Coupe EX

Sup guys!

Just got myself a new 2002 Accord Coupe EX 5-speed. I'm very excited and glad I found you guys here. Looking to change a few things and wanted to see what you guys think:

Any suggestions on how I can add 10 to 20 hp to my ULEV I-4?

Anyone upgraded to 17" rims and what do they think? Looking to swap stock wheels/tires for some 215/45/17's.

How about lowering? What have people done and what do they think?

Thanks so much for any input. Can't wait to get started!
