Gajim is a full featured and easy to use Jabber client.
You are new to the Jabber world and you want to get an account on a Jabber server? Its easy! You first have to choose a Jabber server that offers you the services you need.
One of Jabbers features is that servers provide methods to communicate with contacts on legacy messaging systems, such as ICQ, MSN, AIM, Yahoo, ...
Its not necessary to have every transport youll require, because you can use transports on a server different to that which youre connected to. With that in mind, you should concentrate on finding a server thats fast, and close to you in location (the two usually go together) or perhaps one that has a good sounding name. There is a good list of servers on the jabber.org website.
Another advantage of the Jabber protocol is that you can be connected more than once with an account, with differents resources and priorities. For example, you can be connected at home with resource "At Home" and priority 5, and when you are at work you can be connected with resource "At Work" and priority 7 to get your messages at work.
