Subnet change question

My current network is on a subnet of 255.255.254.0. That gives me 512 IP addresses in a range of 192.168.122.1-192.168.123.254.

If I change my subnet to 255.255.252.0, am I correct in thinking I would now get 1022 IP addresses? And can I set my IP address range to 192.168.120.1-192.168.123.253?

Also, any traps to look out for when changing my subnet?
