I think that most gear should be bought AFTER you meet the baby and find out what baby is like and what baby needs. It also depends, of course, on how the parents want to parent and how they end up parenting.
For us a crib was totally unnecessary, because have a family bed. I know of many people who don't think they will co-sleep, then end up doing so and have an expensive clothes-holder.
We never owned a stroller until he was 2 and we got a jogger, so I don't think an infant stroller is needed.
The only extra "gear" we had was the Fisher Price baby papasan, and that was purely extra, and was used every so often until he was barely 6 months, when he could wriggle out of it (I took the most hilarious series of pictures of him doing that...it resulted in him being upside down, too funny).
No jumper thing, no "exersaucer", no walker (are those even legal anymore? or maybe I'm thinking about Canada)...no pack and play....we did, after he was 1, get an on-the-floor Graco "playpen" sort of thing, from my FIL. We anticipated using it for camping, as a place for him to play and be safe, but he learned rapidly how to climb OUT of it so there went its usefulness for camping! (though he's almost 4, we still have it, and he's been using it this week, LOL)
I'm a sling-addict, but I only started ordering them AFTER he arrived.
I agree with the baby bath sentiments. We thought quite a bit about it, and finally decided on this mesh sling-y sort of seat...I knew that I was always washed in the kitchen sink as a baby, and I love those pictures, and we figured we would do the same...but my childhood sink wasn't near a window, but ours was, and it was drafty. DS hated that. Used the seat thing once in the tub and it was insanely hard on his and he hated it too. Ultimately we just took baths WITH him, and it was all much easier.
I think the way to go is to meet your baby first, and then buy what you think the baby might need. Except for the carseat, assuming the friend uses a car. Other than that, generally some clothes (the simpler the better...short and long sleeve onesies, cotton sleepers, some socks, that's pretty much all we needed) and some dipes (cloth or disposable) and lots of film or memory cards, and that's it until you start getting to know baby and your parenting style.
