We loved the Gerber utensils (they were wonderful for even infants to hold and practice self-feeding). They come in a package of either 3 spoons, 3 forks, or spoon/fork/knife and are very durable and easy to use. DS outgrew them at age 4 so we get a solid 3.5 years of use out of them per child (and they still look almost new!).
We skipped purees entirely so most of the supplies listed were unnecessary for us. Get a few snack containers for out of the house - I have both metal and plastic ones and prefer the metal (but will use plastic if it's a dry item like nuts or pretzels where 'leaching' isn't as likely).
I would advise some good long-sleeved and short-sleeved bibs (Bummies were one brand we liked as well as the IKEA long-sleeved ones). Also, get a package of cheap washcloths or rags to use for face/table wiping - much cheaper and greener to just wash and reuse vs. using endless paper towels.
I would advise using as much glass as possible vs. plastic (see the thread in the Lounge right now about how almost all plastics leach estrogenic junk into our food and bodies). We use tempered glass that doesn't break even when dropped - I love using custard cups by Pyrex for kiddie bowls (we used them even with our infants) and if they got into a 'throw the bowl' stage they were given food directly on the table.
