Buy the Miserly Moms book. You can get it on half.com for next to nothing. It has been such a good reference for me. It has a "recipe" for making wipes. I second the store brand dipes. They work just fine.
You don't need every baby items that comes out. It seems like such a convenience, but it adds tons of clutter. Garage sale now if you can. You can get great deals on high chair, stroller, pack n play, swing, etc.
