There's lots of good cookbooks out there for slowcookers. For a liquid base, you can just use plain ole' water. Or a low-fat chicken or veggie stock. You can find them at the grocery store, in the soup aisle. I've had mine for a few years now. It makes good stews, soups, mac'n'cheese (don't cook those as long though).
Meat cooks the longest, you can put root veggies in at roughly the same time as the meat, but other veggies, such as celery (or any 'above ground' veggies) put in later. They don't need as long to cook.
As for pre browning. Typically, it's not necessary, unless you REALLY want the hash marks from things like grilling. If you get a pot roast, a little browning is okay, I never do though. IMO, it toughens the outside of the meat. Looks nice, but I personally think it toughens it.
I haven't done chicken in mine. i've done pork, beef and veggie dishes only. There are chicken recipes out there... I just havent' tried them yet.
One website I like to get all kinds of recipes from is allrecipes.com
. Just do a search and put in slow cooker or crockpot and what ingredients, like chicken. You should be able to find some listings. I'm not guaranteeing the delectability of some of the ones listed... in fact I have a veggie one that was nasty. But for the most part I've had decent luck. if you want, I can type out some recipes later... just PM me.
