Well, as anyone who has been involved with FIRST Lego League probably knows, doing an autonomous program based purely on timing has issues. Specifically, motors run at different speeds depending on how well the battery is charged. Also if anything gets in your way and slows you down then your program can't account for that. That doesn't mean that this method won't work. You should try it on your robot with a fully charged and a well depleted battery to verify that it will do what you expect in both situations.

The optical sensor MSC will be shipping (correct me if I am wrong) later, what kind of input will it give, will it be a range from 0-255?

The optical sensors in the kit are a digital device, so you just get a 1 or 0 depending on whether the sensor is seeing "light" or "dark". The sensitivity of the sensor is adjustable with a little screw on the back.
