I am looking to upgrade my +3 implants to +4. Is there a particular system that has better prices for these? Should I try to buy them with LP's? Also, what about when I'm ready to get +5's?

Big trade hubs, like Jita(especially Jita), are always a good place to buy anything, be it implants or something else. Also it may be good idea to check some popular mission running systems, like Motsu. Buying implants with LPs is more expensive than with money. You will save way more by buying profitable items from LP store, selling them and buying implants with isk. This is true even for Caldary Navy.
