Net Mask
I know I'm going to feel like a moron when I hear the answer but...My sonicwall LAN interface is set up to 10.0.0.x / 255.0.0.0 but my machines are using 101.0.0.x with a netmask of 255.255.255.0...I didn't set this up , but it doesn't seem to make sense. Am I missing the logic behind this configuration? Also, if it is wrong, how do I change it? I'm not sure how the networked machines are picking up this netmask.

Can you explain how large your network is, why you need some on the internet, some off and in general, just be more detailed? We don't necessarily need every tidbit, but I have no idea if your lan is for 10 people 10,000, if you use Windows systems or Linux or Mac or something else entirely, etc.

Sure
it's a small virtualized network with 5 servers and 50 clients. However, we have a wireless guest network that will occasionally need to support up to 150 connections during large events.

I realize I don't need all the addresses that a 255.0.0.0 mask would allow, but I don't want to reconfigure the DHCP pool for the entire network.
We have a second organization in the facility that leases from us and shares the T1. They are on a class C network (192.198.1.x) and I don't administer their network. So I think my predecessor might have set up our addressing to avoid conflict...but there's no way to tell.

The internal netmask used to be 255.0.0.0 which made subnetting easier. This is how I found the issue. I want to set up a subnet separate from the LAN with internet access only. Of course, when I try to create an address pool of 10.0.2.x on subnet 255.255.225.0, my Cisco WLC gives me an IP misconfig error.
I'm wondering where I set the default internal netmask to 255.0.0.0
Of course, I admit I might be way off in my way of thinking. Maybe I can get a quick education here.
