It may be better to keep the lens and bundle it for sale with the camera body if upgrading that in the future.
I sold my Sigma 17-70mm lens as part of a bundle with my old Rebel XT, and later sold the 70-300mm IS for $400 to a co-worker (probably could have got another $50 - $75 online, but this sale was hassle-free).
The advantage of starting with the inexpensive kit lens is a dSLR newcomer can learn the camera and which lenses he/she needs before spending a lot of money upfront and possibly buying the wrong lenses for his/her use. The disadvantage is many people will quickly outgrow the kit lens and want something else -- although when we travel I see a lot of dSLR users with the kit lens and their camera set to the automatic "green box" mode, because they have no idea how to use a real camera. For those people, the kit lens maybe all they will ever need.
Getting the 18-55 kit lens bundled in for $100 is fine -- you have to have some kind of lens to shoot afterall, and usually, a widezoom is a necessity for a starter.

I was refering to any additional lenses like the 55-250 IS, which is also a kit-level lens. That to me doesn't make much sense to get unless you really don't think you'll ever want to upgrade, which is the case for most(?) casual users. But if your intention is not to be just a typical casual user, then you're probably better off saving up for something much better instead while you work w/ that 18-55 (or anything else you might happen to already have).
I can't imagine the 55-250 IS would sell well in the used market. And if the 70-200 f/4L IS is what you really want, there's not much point in getting the 70-300 IS first, IMHO -- just save up for the one you actually want. However, I'd add that there may be some instances where overlap is fine, eg. owning both a 70-200 f/2.8L IS and some reasonably affordable primes for instance (or a lighter weight telezoom for when you really cannot lug the extra weight). I just wouldn't recommend buying something knowing that you'll likely want to replace it w/ something better as soon as the funds become available. If you think you'll end up wanting to keep and use both, that would be different.
Also, although quality lenses can be resold w/out losing too much $$$ (at least for now), I don't think it's a great idea to depend on that too much when buying a brand new lens.

There are other options that may fit your budget better when you get to them. I read/heard that the Tamron 200-500 is pretty good for ~$850 or so, but it lacks IS. However, for the kind of uses one would want w/ such long teles, you're probably better off relying on some sort of pod (and good technique) instead of IS anyway.

If I ever get a long tele, I'd definitely consider getting that. But honestly, if you're not planning to go birding or shooting whatever real wildlife (or shoot outdoor sports rather seriously ... or run some kind of covert operations

), you're not likely gonna need such long lenses. And don't forget, the better long teles are gonna be beasts to lug around too. A good friend of mine has the Nikon 200-400VR, and that thing dwarves my Sigma 70-200 f/2.8, which itself is not exactly small-and-light.

Don't think just because you can shoot farther w/ a longer tele that you shouldn't rely on your feet more whenever possible (so you don't need the longer tele as much).
