I would send you a link but I'm on my phone:

Google "garrysmod 13 server addons"
or, just go to wiki.garrysmod.com - its on there

No basically.

You don't need a fastdl to add any addons, but any addons that use custom models/materials/sounds will most likely be designed to send those files to connecting clients.

Which is fine, but remember source isn't the fastest file transfer and you can very easily end up with it taking a long time for clients to connect.
