Basic Question(IPSec)

We use IKE PHASE1 to build a Secure Management Connection.Is it true that Secure management Connection is built or protected by defining Transforms?

If we define pre-shared symm key for Authentication in IKE PHASE1.Do we still need to use DH:KEY EXCHANGE PROTOCOL to exchange keys in IKE PHASE1?

If we use DH KEY EXCHANGE PROTOCOL in phase1, then for which purpose we exchange keys and where the key comes from.

Thanks
