I liked the book Le Petit Appetit by Lisa Barnes. Their website has other tips, too. http://www.petitappetit.com/
I also found http://www.amazon.com/Super-Baby-Food-Ruth-Yaron/dp/0965260313 to be helpful, but occasionally annoying. The author can get a little preachy and off topic, and she does tend to make claims that are only substantiated by the anecdotal evidence of her own family.
I second the stick blender recommendation. I didn’t have one when my baby was on purees, but I wish I did! It makes it so easy to make a small pureed portion of whatever your family is eating that meal, as long as the types of food are developmentally and nutritiously appropriate. Clean up is so much less complicated, as well.
I make my own yogurt, and we have smoothies all the time, thanks to the stick blender. You might consider making yogurt from breast milk when it’s time to start solids, although I haven’t done that myself (my supply was too low for culinary experimentation).
As for teething, we had a knotty doll similar to this made from organic terry.

It wore well through the first year, going through the wash at least weekly, but then began to look grungy, so I made my son a new one. He chewed on it thoughtfully, then handed it back to me, and demanded his old doll back. The old doll is positively tattered now, but even at age 3, it remains among his beloved bedmates. The new knotty doll got adopted as a buddy when he was no longer teething, so it still looks pretty good.
My recommendation on teething tablets is to make sure you research every ingredient in it, as you are giving it to a baby (obviously). Herbs are not inherently safe just because they are natural (cocaine, marijuana, and tobacco are natural as well). And just because they are designed for babies doesn’t mean that they are necessarily “safe” either. An overdose of Oragel can be fatal.
