Kathy, look at the temperature ranges of sleeping bags and what you're likely to be using them for. I've got an all singing all dancing goes down to a minus gazillion. Great when its really cold, I've also got sleeping bags that have less of a rating, I was sleeping out the other weekend and took a 3 season bag as I knew I'd be warm enough. You can always wear clothes in a sleeping bag or put a coat over the top if you're cold, on the flipside, you can unzip a bag if you're too warm.
As for stoves, it will depend on how 'adaptable' you need it to be, will it just be for using in the kitchen or garden or do you anticipate having to lug it somewhere ?
If its the former, a couple that Andy has suggested are perfectly adequate, I've got a few of the briefcase ones, the missus keeps one up the allotment for brews and they're very quick to boil. These ones (of Andy's) fall into this category.

Shop around,some of the cheapy shops sell the first one for less than a tenner.
If its something you want to be able to pack then weight and size are issues and there are loads of options, both in the fuel and the stove itself, its a bit of a personal choice thing with advantages and disadvantages.
Have a read of reviews of stuff, even on sites that you don't intend to buy from and if you can get out to some outdoor shops to get a (literal) feel for the equipment and see what works for you, that's the same for any gear, you can't bet hands on.
