Toyota Repair: High mileage maintenance, toyota solara sle, toyota solara

Question
I have a 2000 Toyota solara SLE with 180,000 Miles on it. To date I have had no majors problems with it and it's been an excellent car. Besides the routine fluid changes,brakes,and tires what else should I be concerned about with such high mileage?  I commute a long distance to work and would like to keep it running as reliably is has been for at least 30k to 40k more miles before i replace it.

Answer
The timing belt should be replaced every 90,000 miles, the spark plugs every 60,000 miles, other than that just keep doing what you have been, by the way, when replacing the timing belt it may also bee a good idea to replace the water pump and the drive belts and maybe the front engine seals.
