Can i use SSH and IP tables to secure my server, even when i use wireless to access my server? My IP address appears to be dynamic each time i connect via wireless. What would be my options, and what would i need to look out for?

Trying to secure a server you administer over the public internet by limiting which IPs can be used to administer it is a good way to lock yourself out. I wouldn't recommend it. Additionally, the technology you use to connect to the internet doesn't really matter at all in this case (you do know about the OSI model, I trust?).
One doesn't really use SSH to secure a server. It's just a more secure way of accessing it than telnet, with the added ability to create tunnels as needed.
Really? You would be much better served by setting a strong password, using client SSH keys, and not setting an IP ACL.
