Your PC has one address space, don't use that for your static addresses.
tunk's offer is fine, regular routers don't use that.
Maybe better use 33 for 3rd octet, if you're in a bigger facility.
Last octets as 2 and 3 are also fine.
If default gateway is required you can use basically any value, for unknown address there is a timeout, but it shouldn't be a real problem.
Using PC's address as gateway address for scope is probably also fine, but you never know if M$ is your PC OS provider.
