When painting, do you need to prime the wall if the new color is much darker than the old color?
Answers:
Priming is a good rule of thumb, regardless of color changes. If you really don't want to prime, I suggest using Kilz 2, at least. It will allow the new color better adhesion and you will get a better finished product. Remember that one gallon will cover 350 square feet in one coat. You may need two coats.
If the current paint on your wall is eggshell, it won't matter what the next paint sheen is if you are going to prime. Eggshell is highly scrubbable and cleanable (if you get stains, crayons, etc on it). Satin is less scrubbable but more washable than eggshell. Semigloss, of course, is the best in terms of washing off stains, but it sounds like you don't want something with a lot of shine. Eggshell is my personal favorite, especially for how it looks when it dries. Flat paint 'grabs' fingerprints, meaning you can see the fingerprint you left there on the wall. It is the most durable and most scrubbable (how much you can scrub at it until the paint itself comes off).
Home Depot is having a sale on Behr paint: $5 off one gallon cans, $20 off 5-gallon buckets by mail-in rebate until tomorrow, January 16. Cashiers can print two receipts so you don't have to mail in your original.

I hope I have answered your question and good luck with your project.

Prime any bare spots or repairs. You might get away with one coat of new since youre going from light to dark. Use the best quality paint you can afford and preparation is everything!

You should nt have to prime. If the current paint is glossy, you should sand it a little bit to help the new pain adhere to the old.
Since it is white, no, if the paint is glossy, you may need to though. It worked fine when I painted my room.
Tinted primer costs less than paint and does a good job of adhering to the existing painted wall. It's a good idea to do a coat of tinted primer followed by one or more coats of your chosen paint.
