Answer 1

Salesforce Callouts have certain limitations and the one that you are hitting is:

"The maximum cumulative timeout for callouts by a single Apex transaction is 120 seconds. This time is additive across all callouts invoked by the Apex transaction".

You can find the other limitations here: Callout Limits and Limitations

I believe it would be a good idea to convert the implementation into a Batch job and set the appropriate batch size by benchmarking so that it doesn't hit the Max Callout time allowed.

Here is the developer article on how to use Batch processes: Using Batch Apex

Go through it and let me know if you have any questions. Also, post to the thread if you need any additional info about Batch processing.
