Your question is not totally clear, so I will try to guess what you need to know!
The point of a VLAN is to separate devices, so without additional configuration, devics will not talk to those in a different VLAN.
The normal method to allow the devices in one VLAN to talk to those in another is to enable routing between them. That could be by an external router, but as you have a 3750 the best way is to configure it locally.
You need to have one subnet allocated to each VLAN. I will use 10.1..0/24 to illustrate.
ip routing
Int vlan 70
ip add 10.1.70.1 255.255.255.0
no sh
Int vlan 71
ip add 10.1.71.1 255.255.255.0
no sh
Int vlan 72
ip add 10.1.72.1 255.255.255.0
no sh
Int vlan 73
ip add 10.1.73.1 255.255.255.0
no sh
and so on for all VLANs. Every device in each VLAN will need an IP address in the range 10.1..2-254, and a default gateway configured of 10.1..1
