What's a good product to use the smaller ones with? Amazon sell anything good?

You question makes no sense at all.

If needed, can these be cut to fit a specific size of funnel? Or would I be better off just buying some of the square filters and cutting those?

Buy the correct size for your Buckner funnel; if you are using a gravity funnel, look up how to fold round filter paper for this type filter.
