As a rule will all Gateway Router IPs generally end with a .1 ?

No, some end in .254 or other variations for network security reasons. .1 is just the most common. -
Hi Larry, as ITPro1 said, it could be anything really, and usually depends on the vendor of the equipment, but .1 and .254 are the most often used. I always visualise those IP's as the edges, if you will, of the network, which is where i want my gateway to be. Myself, I will generally use .254

Not always. We do this on our shows because it's easy to remember for the example. But as mentioned by others in the their reply, You'll see them with different numbers for the default gateway. Many people have adopted using the first address in the range of IPs (e.g. 192.168.0.1 /24) or the last address in the range (192.168.0.254/24) makes it easy. But that doesn't necessarily mean the first or the last address will be one of those two numbers. Let me give you an example. What if my IP address range was a subnetted range: 192.168.0.16/28. There wouldn't be a .1 or a .254 in that range of IPs. But to keep the coventional wisdom of First or Last address as being a gateway here the IP might be 192.168.0.17/28 or 192.168.0.30/28.
So remember, even though you're more likely to see a .1 or a .254. It's not because of the numbers but usually it's because it's the 1st or the last address in the IP address range. But it could be any address that you would choose as long as it's within your range of ip addresses.

It can become just the convention that you (or the place you work for) adopts (like whether you wire 568A or 568B) if you do a bunch of subnets. I'm usually a "broadcast address minus one" (and 568B) guy. Don't get trapped into thinking it is all a /24 world.
A good subnetting practice link is http://www.subnetting.net/Subnetting.aspx?mode=practice, some questions will ask the first and last valid host addresses, which will be where either camp (network address plus one, or broadcast address minus one) will place their gateways....
