Timing belt broke/shreded on a replacement engine with low milage...

The belt snapped previously, and I took my mechanic's advice and replace the engine with a low milege one from Japan. However, only 10K miles later, it snapped again and he's no longer in business.

Could I replace the timing belt to get the car running again?
How would I find out if the valves are not bent?

What other parts should I consider replacing with this job?

Anyone with a pdf service manual?

In addition, I any clues on fixing the suspension???

Thank you in advance for your postings...
