Okay, let me start off by saying that I'm writing this message on my iPhone on the way back from looking at the car ( don't worry my dad is driving

) and I really liked the car but it has a few issues and I wanted your guys' opinions.
The car is a 2001 xls pearl white with gray leather, and is fully loaded minus heated seats and navi. It has 91xxx miles and I get a good impression of the seller. Now on to the issues: the car has not had the timing belt, waterpump, or tensioner pulley replaced, has two large cracks in the windshield and will need new tires soon (5,000 on fronts, 10,000 on rears). However, the main issue is that the car has some minor hail damage on it. Nothing huge but I'm just not positive on how much this will affect my satisfaction with the car. The asking price is $8500 but I'm pretty confident that I can get it for $8000. Is this a good deal?
Also, the car has a light on in the dash that is a symbol that is of the car in amber with an indication to the rear of the car, what is this? I forgot to ask him and figured you might be able to help. Also there is a minor squeak at idle from near the alternator, is this a sign of replacement? I really like the car, and my financial situation limits me to pretty much either a 1st gen or this car.
Thanks in advance for any help/advice you can provide!!

Edit: Also is it necessary for me to the timing belt etc. replaced immediately or can I wait a while? If so, how long? I've heard both sides that the 3.0 is a "non-interference" engine but was not sure if this was true.
