How to configure stack of 7?

You wire the stack together using it's stack cables.  Then you configure stack,which will behave like a single switch but with banks of ports (from each stack member).

With 3750 stacks, its "easiest" if switches are similar, including series family, IOS version and IOS feature set.  (NB: if you have an 3750G-12S in your stack, you'll also want all stack members to use same SDM template.


How to connect to core switch?

I would suggest Etherchannel, using ports from different stack members.  Cisco suggests, for 3750 stacks, the active stack master not host an uplink port.
