I have 35,000 miles. Do I need to replace my timing chain for this model before I hit the 50,000 mark?

No, you don't. Timing chains are not regular maintenance items, and they don't need to be replaced unless there is a repair that needs to be happens.
Check your owner's manual. If you have a timing belt, and not a chain, it will need to be replaced at an interval defined by the manufacturer.

The Scion XB has a timing chain. I haven't seen any problems with them, two customers have 100,000 to 130,000 miles on theirs no problems at all.

I have one customer with 190,000 on the same chain with no problems, not a wear item unless abused.
