Advice Needed

Ok - calling all moms and all people that know moms for advice.  I'm starting to get to that stage where I feel very unprepared for this baby and very overwhelmed with what items are needed and what items are overkill.  So far I have purchased a crib, a mattress for the crib, a swing (recommended by a friend), a stroller and a car seat.  Other than that, I'm at a loss for what I really need. 

Let's start with diaper bags...we all know that I will NEED one of those but I keep going back and forth with what I need in a diaper bag. I'm trying to balance my superficial desire to have a cute bag with the need for space and functionality.  Here are some things I think are important:

* Big enough but not too big (how is that for specific - hee hee)
* Zipper top - I would lose things if it tips over which it inevitably will do
* Non-black liner.  I've heard that it is difficult to find items with a black liner
* I like the idea of it not screaming, "Look at me...I'm a diaper bag" since it will most likely double as my purse when I'm with the baby.

Here are some options that I like and would love your input:

Beyond the superficial diaper bag, tell me what you couldn't live without (or your friends with kids couldn't live without)...I still need advice on:

* Carrying sling
* Bottles
* Swaddling Blankets
* Diaper products
* Hygiene products
* Bouncers

What else?? Help!!!
