You'll have another choice in less than a week when Sony announces its advanced amateur model, probably called the A300.
Anyway, for general advice on your first DSLR purchase, you have plenty of time between now and March to learn how to use your camera.
First off, I wouldn't worry about macro just yet. The dedicated lenses are quite expensive (for good ones, anyway -- $400+ starting with 100mm), and the techniques are fairly hard to do right off the bat. If you get a lens with a macro capability, like some of the 70-300s out there, that's a good way to start because you aren't dropping a sizeable chunk of cash on a single purpose lens (they can be used for other things but aren't quite as useful -- portraits tend to be VERY sharp, showing off all skin imperfections, for instance).
Second, I'd start with the kit lens and a consumer telephoto (70-300) or perhaps with a "travel zoom" like Tamron's 18-250mm. Learn the camera body, learn where you like to shoot, and then start investing in quality glass as money permits when you figure out what suits your style. The great thing about lenses is that they really don't lose their value so if you buy one as a starter, you can sell it for nearly what you paid -- consider it a rental. Also, if you know anyone with the same camera line, try using some lenses (go on shoots with other people) to see what works and what doesn't. Take a class or two sponsored by a lens manufacturer, which should give you the opportunity to use a variety of their lenses.
Personally, I used to think I loved telephoto, but now I'm about to sell my 75-300mm lens because I just never use the long end -- I've found 210mm to be adequate for the majority of my needs at the moment. I've invested in some quality prime lenses (I have 28mm, 50mm, and 100mm -- need an 85mm), and I love shooting with them though I always thought I preferred zooms. Until you start shooting a LOT, you will likely not know what you like to do and what suits your photography style.
Third, check your tripod. If it's a consumer grade one (anything under $75, and that's being miserly), you might consider an upgrade. If you're planning on a lot of hiking in Nepal, you need to look into something lightweight, portable, but strong. That translates to expensive. Trust me -- you don't want to lug around a massive tripod when hiking as you'll just be miserable.
Lastly, don't forget about a quality flash. The onboard flashes of ALL cameras just suck. If you want to do any portrait photography or people photography on a cloudy day, you'll likely want an external flash. Get the higher caliber one for whatever line you pick -- mine was $350 and absolutely worth it.
Bottomline: Go general first and then specialize. I wouldn't reach on the camera body, personally, but I also wouldn't overspend on lenses right out the gate. It would suck to have a great camera body, a fantastic lens, and then realize you don't have the money for a high quality large diameter circular polarizer to make those landscape shots look spectacular.
