Just a couple of comments...
We didn't co-sleep...we used a crib, but the pack 'n play play yard was great when I wanted to work outside in the garden and it was baby nap time. I put the sun-shade up and she slept outside in the fresh air. Also when we traveled to visit family since we don't co-sleep it was helpful to have a bed for DD.
Never used a diaper changing table...just got a bunch of waterproof pads and put those down in the crib or on our bed covered with a cloth diaper when we changed DD.
Never used a baby tub...seemed like a waste of money when I could clean out my sink and put a big fluffy towel down and then fill the sink with lukewarm water. When she got bigger and a bit more fidgety, I just crawled in the big tub with her.
Didn't like the front carrier because I always felt like the baby was getting too warm in it. Will try the sling this go around.
I found our rocking chair uncomfortable for nursing, but we recently purchased a chair from IKEA (can't remember style name of chair but you'll know it when you sit in it...MMM!) that has a bit of a bounce to it if I need to rock the baby, and a foot rest as well.
You don't need a fancy-schmancy diaper bag but any bag will do. I found backpacks were helpful after a while. Just be sure it is pre-packed with the stuff you need so all you have to do is grab the bag and lock the door behind you when you are inclined. I had a a girlfriend that took HOURS (well...maybe not HOURS
) to get out of the house because she repacked her diaper bag just before we were ready to leave EVERY TIME...UGH! If you are using wipes (we didn't because DD developed a rash early on from them...even the hypoallergenic ones) have them in a small baggy, toss in a few diapers (cloth or disposable depending on preference) and don't forget a ziploc bag to put the dirties in!! Some rattles, a book or two and a changing pad (see above...waterproof pad and cloth diaper!) and you are ready to go. I found it easiest to repack the bag when I returned rather than waiting until I was ready to go...much quicker. You have to empty the dirty diapers anyway so might as well pack the stuff all up ahead of time.
We had a jogging stroller but I rarely used it because I gave up jogging (had knee surgery 6 months after I had DD). I agree, however, that it is great for city use, particularly if you are using it on uneven sidewalks. It is also great for "country/off road" use because the tires are pretty sturdy.
If you are using cloth diapers...either get a delivery system or purchase diapers/wraps/pail/etc. If you are using disposables, 'diaper genies' help keep odor down. We used an excellent delivery service until we moved to a place that didn't have a local service. Used disposables (mostly Tushies and Huggies) for last year of diaper use (between 2 1/2-3 1/2 yo).
Since I was a working mom, I needed a breastpump. I had a friend who could hand express like a champ but I never got the hang of it. I got a small electric/battery pump from Medela and it worked marvelously.
Last bit of advice...I'm not one for shopping at Baby Gap (TOO EXPENSIVE AND TOO TRENDY) but I got a pair of socks from them for a gift and they NEVER fell off of my DD's feet. All other socks did!!!! I vowed at that point that my children would never wear anything else but Baby Gap socks!!!! They have NEVER let me down!
We were d-mn poor when we had DD and we made it with second hand stuff borrowed from friends and also purchased from "Once Upon a Child"...even with a decent income now, we expect to do the same for baby #2! Keep it simple...babies don't care...they just want you to hold and love them!
