I have Sven as my follower at the moment and I've given him some Elven Armour (Light) and an Ancient Nord Battleaxe (2h), but I have no idea if these items work for him or not.
Do the followers have stats and skills already? I read on the wiki that Lydia is a good thief, and I know Sven is a bard. If he's a bard, then Bow and Dagger surely?
Or do followers work like the player and what items you give them shape their skills?

Followers are generally given a set of skills that will improve, regardless of what you equip them with. These will improve with level, but nothing else will. Faendal is always going to do better with bows than with a greatsword, for example.
To this end, the official strategy guide states:
It's not clear where the rumor that Lydia would make an excellent thief started: UESP mentions she has the sneak skill on the list of followers (I suspect that's where Wikia pulled the information), but her wiki page clearly marks her as a warrior (the correct designation). Nothing about her says "stealthy": she starts with a sword and board and tells you over and over that she's there to protect you.
While the official strategy guide does list what each follower's skill is, with the exception of Lydia, UESP's version matches up with the strategy guide, so it should be pretty accurate to determine what skills your follower has.
But if you wanted to do it without consulting a guide or a wiki, it's generally common sense and usually based on what equipment they come with. Lydia comes with a sword and shield, so her skills are one-handed and block; Faedrun comes with a bow, so one of his skills is archery; and so on.
