Well if you want them, the healing period is worth it. And it's not too bad -- just leave them alone for the most part, maybe twisting them occasionally to degunk the crust that forms around the holes. Whatever you do, don't take them out while recovering or they will heal over quickly. I took mine out to take a shower after having them done the night before and my nipples began to go back together in just 30 minutes. I had to push the piercing back through my stuck-together skin and it was highly painful. But worth it.
My piercing shop also recommended the bars for a first-timer, as it allows your piercing to set up correctly. I wouldn't advise going with the hoops because it might twist your piercing outward and ultimately not set up as good as with the bars.
I didn't find it to be that painful. But then again, I got extremely drunk before and after my piercing (sober 2 years now, for what it's worth). If you can do that, it might help if you're afraid of the pain. Just go with a friend and don't get too carried away 😉
