With a netmask of 255.255.255.0 or /24 in alternate terminology, you
theoretically have 256 individual IP adresses.
The last address of .255 is called the broadcast address and has special
meaning to devices on the network.
The first address of .0 is called the network address and is most often used
when specifying routing.
This leaves a valid range of .1 to .254 for your individual hosts. Routers
will most often be set to .1 or .254, so the safe range would be .2 to .253.
If you want your device to talk to the outside world, then you will need to
use an IP address that is in the range used by your router/gateway device. To
find this information, log into your gateway device and look at the configuration.
This is a very simple explanation and misses out on some details. For most
people, DHCP is the easiest way to get running on a network. Since you are not
familiar with TCP/IP networks and terminology, I suggest you work on getting
your gumstix dhcp working as it will make your life much easier.
