New Rider, First Bike & Lots of Questions

[kedebrav00]

Hello, I have just learned how to ride a motorcycle. As you may guess I am learning on a GZ250. I decided to buy a used GZ250, as my first bike. I figured it would help me get comfortable on the road since its the bike i'm learning on and it's the rated the best beginner bike. Since you guys seem to know a lot about GZ250 I wanted to describe my bike and ask a few questions. please let me know what you think.

Bike Details:
The bike I am buying is a 1999 GZ250 it has about 1700 miles on it.
It was own by a motorcycle school.
it has one dent on the gas tank
when I went to look at it didn't start right away the guy selling the bike said it was the battery and jumped started it.
The cost of the bike is $650.00


Questions:
(1) Am I getting a good deal on the bike. I couldn't find any blue book value for used bikes?
(2) Should I ask any question in particular before buying the bike?
(3) I live in New York and the bike is two hours away. Do you think its a good idea to ride the bike to the city?
(4) Anyone know any good place in New York TriState Area or Online to get Used Accessories - i.e(Used Helmet, Jacket, and
Boots)?
(5) I've posted two pictures of the bike if anyone can pick out some anything suspicious let me know.
