I want to agree in part and disagree in part with audiobomber's post.
I think audiobomber's lens recommendations are pretty good. The 16-45 in particular is one of my favorite lenses. Perhaps it is my very favorite, I'm not sure what I like better. I have the 50 f/1.4 too but the truth is that I don't use it that much, because, well, because I usually prefer to use zooms for what I believe are good reasons. The majority of my shooting does not allow me to zoom with my feet.
Here's the part with which I must respectfully disagree:

Not true, I'm afraid. LBA has nothing to do with what you've spent or what you've got. That's why the "A" in LBA is there. This is like saying to an alcoholic that getting really plastered is going to help him stay sober afterwards. :-)
I joke, but actually this is semi-serious. We live in a consumerist culture and camera equipment is hot stuff with a powerful appeal to those of us who are into it. It's important to realize this, because photography can be an expensive hobby - and the urge (the compulsion, if you will) to buy new stuff can actually make you nervous, unhappy, usually because you know you're being tempted to spend money that perhaps should be spent on something else (like, say, food or rent or clothing for your children).
It is not at all a bad idea to spread out your purchases. Buy the body + the 16-45 lens and live with that for a month or two. THEN get the 50 f/1.4 and work with it for a while. THEN get the 55-300 or whatever you want next. This will give you a bit of a release from time to time and will
manage LBA more responsibly - which is about all you can do with LBA.
But spreading your purchases out like this actually has another good benefit. As you work with a lens - any lens at all - you learn things that will help you with your next lens purchase. If you buy three lenses all at once, before you've become really knowledgeable about this stuff, then you're making three purchases without really knowing what you want. If you spread your purchases out, on the other hand, your second purchase will be made a bit more knowledgeably than your first, and the third will be even smarter. There's a lot to learn, not just about lenses but about what kind of photography you're going to do, so you aren't going to achieve "expert" status by your third purchase or even your tenth, but you'll know a bit more each time.
