First, what is a recommended brand of food?: there are lots of good brands, I like Innova, California Natural, Canidae and Taste of the Wild.
What treats are good for them? Or would they prefer bones?Well you'll need training treats so anything small, I usually just use regular meat but you can but them too. Look for treats with meat in them no corn or wheat. For treats that consume time RAW bones (supervised), kongs and other food filled toys that make them work to get the food out are great.
How to crate train? Crate training is great for housebreaking dog so I'm glad you're looking into it. Basically start putting her in their for short times everyday. You can start just by tossing in a treat, she goes and gets it then comes back out, that's it. Then start doing it but closing the door for just a second and letting her out. At night she sleeps in there, next to your bed is usually best. Feed her in the crate. Give her a raw bone if you are home or a stuffed kong/other food dispensing toy if you are gone (or home). At first you may want to leave a shirt that smells like you or a toy from the breeders if they give you one, so that the scent makes her feel secure. Sometimes a ticking clock (which mimics the mom and siblings heart beats) wrapped in a towel next to or in the crate will help soothe the pup. The key though is to never give into barking, whining, crying or screaming in the crate. The only exception is once in the middle o the night since young pups will still have to go once or more in the middle of the night (with a large dog like a lab I'd say once is enough assuming she's at least 8 weeks). That's the basics at least, you might need more info on how to use the crate most effectively but that's more info than you probably want right now.
What type of toys should I get?I already said kongs and other food dispensers so from their it's up to you. Some dogs like stuffed toys (but beware if that's all you get they may never like rubber toys) and others like rubber ones. Get tennis balls, a lot of dogs like toys called Cuz (

If you have a really destructive dog You'll have to stick with strong toys like tire biters, kongs and nylabones (some are stronger than others).
And finally, anything else I can do to make the puppy comfortable?Just make sure you give her lots of love and socialization early on!
And pick up some good books, check out these:
