Semi-New never really posted

I've had my 2008 Yaris since June of 2010, and I love it, I've known about this site since before I bought it however I havent really browsed or posted, Here's some info on my yaris

2008 Red 3 Door
55000 miles (was about 45k when I bought it)

4 Speed Automatic (When I bought it I was uncomfortable with Manual but now I wish I went with manual, I might possibly convert if possible)

Basic as basic can get (Roll-up windows, no electric locks) but I think I like it that way for some reason

I was wondering, money not being a huge factor, what is the first thing I should do to it??? I want to get very familiar with the technical part of it, I would like to install a digital Speedometer (the standard one is off a little a reading of 70 is actually about 65) also would like a new audio system, but I am very open to more important or useful mods I should do first
