Firstly, welcome to FFXIV.

Since you're both new and looking for people to show you the ropes, I recommend you find an FC early on. Plenty will be willing to take you even from your earliest levels.

That said, I do not recommend you use the forums to find one; only a small fraction of the people in the game ever read them at all. Instead, I'd suggest looking around in game... but also, make sure to ask a few questions before just accepting the first random invite. Talk to recruiters about pretty much what you said in your post here; Make sure it's an FC with members willing to spend time helping newcomers, and a decent number of them.
