I'm currently designing a Lap timer using a SparkFun 20X4 Serial LCD and I was wondering how to set the cursor where ever i wanted. Any ideas? I'm using the Duemilanove if that changes anything.
Yep, there is an instruction for that (assuming your 20x4 is based on the HD44780).
Check here...

(see "Instruction Set" link)
Or download the datasheet for the HD44780.
LCD.print(0xFE, BYTE);
LCD.print(130, BYTE);
Third position on first line.
