Tacoma Maintenance, Newbie question Options

[FTCHARLIE]

Hi - New to this site and forum. I'll get to it. 2000 Taco 4 cyl stick w/ 118,000 k. She's in desperate need of a tune up and I was hoping you guys could give me some no bs advice. I've called around and evey shop has a different idea as to what should be done. One guy said that I should replace the timing belt ?? I thought this model has a timing chain which should be good for 150,000 k ??? Anyways - I've just had basic service in the past - oil filter, air filter etc. I did a search with no results so I hope someone can steer me in the right direction. Thanks in advance.
