Servicing advice for 03 corolla ce

[ssexna]

HI
I have a 03 corolla CE. I have done only 17,000 miles on it, and now am completing 34 months (bought in Jan 2003).
TIll now I have been getting the usual oil & filter change service every 4 months or so. This time my local dealer suggested I get the 30,000/ 2 year maintenance done for $470 or so. PLease advice the following:

1. Which service is advisable? Usual $29 or $470
2. What place - Toyota dealership or some other place
3. Future servicing schedule for low mileage car like mine

I am in Dalllas TX so it ain't too cold here for anti freeze things etc

Any advice will be appreciated
thanks
