Newbie question: Should I change my tires if...?

I have less than 500 miles on my new Trek 2100 which has
stock Bontrager select tires. Last weeekend I had a flat due
to a puncture through the tire from a small rock. THe
puncture hole is maybe 2mm, should I buy a new tire, or set
of tires, or should I just place a patch in the puncture
hole on the tire? I ride suburban Philadelphia streets, so
there is plenty of debris. My concern is having another
blowout while screaming down a hill.

No need to replace the tire. Just "boot" it from the inside
with a dollar, a thin piece of cardboard like from a candy
bar or something.
