In many cases you can use Nikon's CLS (Creative Lighting System) and won't need the SC-29. CLS gives you a lot more freedom about where you place your light stand, however, it does have it's limitations in bright sunlight.
Regarding a stand - rather than talk about brand names I'd say that you want a light stand that is sturdy, has a wide base and the ability to place sandbags for ballast when shooting outdoors. Reflectors, softboxes and umbrellas make excellent kites! I usually buy 13ft stands so they can be used for overhead lighting in addition to regular face-level.
Many stands come with only an attachment post at the top and require a separate light and umbrella shoe mount clamp to hold your umbrella and SB-700. Take a look at B & H, Adorama, Amazon, etc.
