1. There is no set structure for IP addressing, but since most deployments are not Internet-facing it is a standard recommendation for this and most other networks to use private addressing - within the available ranges you use whatever is appropriate for your network.
If for example you have your LANs in the 10.1.x.x range, it might make sense to use a parallel range such as 10.2.x.x for ease of recognition when troubleshooting etc..
2. Many deployments allow full routing between the subnets - however if it isn't required it makes sense to limit traffic to the Voice network in order to give further protection to your voice servers...

Take a look at the callmanager solution refferrence network design guide for deployment and design examples,It allways best to use voice and data vlans as they help you to prevent ur data traffic overwhelming the voice traffic.
Just want to tell you that if your network is really small and you have a very small number of IP phones, then you can use the phones in the data vlan, but if your network is medium to large or, might expand in the future, please use different vlans for your ip phones and other devices on the network. This makes troubleshooting easier and there isn't any fear of collisions on the network, which will surely bring down your voice network.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
