Its always best to renew the chain and sprockets in one hit. The Sprockets that you have now may look ok but may well wear out quite quick after putting on a new chain. May even affect your new chains performance??
If putting a new chain on old sprockets was a quick fix for example, say to get you home after a breakdown then yes, but not as a rule.
As for what make? Renthal seen pretty good to be honest. If in doubt, give them a ring etc.
