I have just taken over a Switch that is a 3750 stack with port channels.
What is the purpose and how do I see how many are configured and what ports are apart of these?

Port channel bundles switch ports to provide agreegated speed. To display participating interfaces, do a "show etherchannel sum"

Here is the output

Switch#show etherchannel summary
Flags:  D - down        P - bundled in port-channel
        I - stand-alone s - suspended
        H - Hot-standby (LACP only)
        R - Layer3      S - Layer2
        U - in use      f - failed to allocate aggregator

        M - not in use, minimum links not met
        u - unsuitable for bundling
        w - waiting to be aggregated
        d - default port

Number of channel-groups in use: 1
Number of aggregators:           1
