Not knowing if it is java or L2OFF is not a good start to you trying to host an L2 server, but as for that pack it is L2j. If you cannot tell the different between them then I strongly suggest doing a lot more research first.
Running a server plus logging in from the same machine is not a good idea, you will get massive lags; even worse is that you want to use a laptop. You playing and letting your friends log in will result in them having tons of lag even though it is on a local network.
To be honest I do not think you should try running an L2 server, you lack the knowledge even to tell that is java or L2OFF. There are many guides you can follow on here and by doing a Google search.
My honest opinion of your idea: bad.
