Um, get that belt changed ASAP!!! You only have 16k on the car but you have a rubber part that is almost 20 years old. Belts get old and brittle, and it will break and ruin your day and the engine.
The Timing belt change is not really that hard, just take your time and document everything. I would recomend someone that has done one on a 4 cam engine before. If you don't know anyone, follow the FSM word for word. The best advise, when you get it on, count the cogs before starting it up. This is the only true way to make sure it is on correctly. Don't cheap out on the belt and bearings, as this is vital for the engine. The best kit that I have found, not price wise but kit wise..

Gates and GMB are just fine and have had no issues with them. Upgrade to silicon bypass hoses, ramey idler studs, and the little things like that. Well worth it, just think of it as cheap security. Yes I know it gets expensive fast, but think how much a rebuild or new engine will cost.
If you need help or have any questions, all of are here to help and some have done multiple changes.
