Timing Belt Change. What else to change?

Hi everyone, great site its been a lot of help with great info.

My 2005 Accent has 130,000km/80,000 miles and I will be doing the timing belt for the first time. I am not very good with cars so I will be bringing it in to a mechanic to do. I am on a very tight budget so if anyone has any suggestions of a good shop Markham/Toronto area that is cheap let me know.

I joined to ask for recommendation on what else should I change? I will be grabbing gates belts from Rockauto (timing belt kit, 3 other belts). Also reading though these threads it seems like a good idea to do the water pump. Can't find a quality pump for cheap so I figured to grab one from Hyundai (about $100 tax in).

So the belt kit comes with the belt, tensioner, and idler. Do I need the seals that I see in other kits? Where can I get them?

Anything else that I can do now for cheap that would save me money down the road? Hopefully nothing very expensive, might not be able to afford it.

Also one last question about the water pump. Do I need to change it? I was told that labour would cost an extra $50 (including the fluid). Plus the $100 I am going to give Hyundai for the pump. Just wondering what you guys have experienced with water pumps.

Thanks for your help.
