Excited new 2007 prius owner

Picked up a CPO 2007 Prius Package 2 this weekend in Super White after a month of research. I stumbled onto this site while doing my research and I think it helped in making an informed purchase and cleared up the misconceptions out there about the Prius. Thanks guys!

I still have my 2004 X5 (and LOVE it), but the new Prius will be the daily driver. I've already driven 100 miles and averaged 46.9 mpg, so it's a HUGE improvement over the 14.9 mpg I used to get.

Still not sure what mods I want, but I'm thinking;
TRD Sportivo Suspension Kit
Sway Bars
Tower Brace

I want to tighten up the suspension a little bit to reduce brake dive and lift and lean in turns, but I don't extreme go cart handling.
