Hello @richiebarista, Welcome to Connect. To your first question I'm not a doctor but I don't think gabapentin can cause neuropathy but there is another discussion where members have discussed the question Can Gabapentin make neuropathy worse: https://connect.mayoclinic.org/discussion/can-gabapentin-make-neuropathy-pain-worse/.

If you are looking for studies and research type papers, Google Scholar is a good tool and lets you sort results by year. Here's a search using "can gabapentin cause neuropathy" with the most recent results shown - https://scholar.google.com/scholar.

You can tweak the search phrase and find something more specific if you want.
