Apart from docs... (but I also suggest reviewing quite few of them) - apart from above also versions release notes, scaling JIRA docs (https://confluence.atlassian.com/enterprise/scaling-jira-7-7-943526476.html) etc.plus this one: https://confluence.atlassian.com/doc/performance-tuning-130289.html

1. Volumetric - of course number of business objects affects JIRA (mostly indexes and R/W operations) - there are even some Atlassian studies like: https://confluence.atlassian.com/enterprise/managing-custom-fields-in-jira-effectively-945523781.html

2. Architectural/Technical - there is a number of known issues or "DO NOT DO THIS AT HOME" topics - few examples here:
https://confluence.atlassian.com/jirakb/crashes-and-performance-issues-troubleshooting-203394749.html

And here: https://community.atlassian.com/t5/Marketplace-Apps-questions/Can-Script-runner-cause-JIRA-to-run-out-of-memory/qaq-p/400929

So simple answer:

1. Yes - fields and PFs (post-functions at lower level) can affect performance - due to volumetric rather, than fact they use scripts.
2. As for scripts - it is rather about volumetric (again) and script code quality.
