The best way to do this is to keep both 3750's separate , run a gig trunk link between them , allow all your vlans across this link . Set both 3750's as vtp servers and the switches below as clients . configure your vlans , layer 2 and layer 3 SVI's , setup with hsrp on your SVI's on each 3750 then setup your trunk links down to your access switches . This then gives you redundancy if you lose a link to the access switches or if one of the 3750's takes a nosedive.
I you connect them as stack, the switch will look like one STP ID. This means that you should look at it as one single switch. There will be no nead for HSRP because the switch is sharing MAC address for gateways. If primary fails Sec will still hold gateway active.
The next thing to think about is etherchannel, access switches i now connected with 4 cables to one switch
