If you're running DNS cache on the router and the LAN hosts are using it, the answer to #2 is probably no. dnscache should start with the root name servers and work their way down to resolve names. Charter's DNS servers should be bypassed completely unless you're resolving a name for which those DNS servers are authoritative. The exception is if you explicitely configure it to forward all queries or certain domains to Charter's DNS servers.
