Camera
Any entry-level DSLR will be excellent. The questions Akram Mellice pointed out:
as well as How much do lens lineups vary across DSLR platforms? can help if you need more of a starting point, but really, you'll do fine picking something that your friends have or that appeals to you more than the others for any reason.
Review sites make their money in pointing out differences, and so have a natural incentive to accentuate differences and to make it seem as if one choice is miles better than another. This is false. All modern DSLRs are astoundingly excellent, and the distinction isn't A vs. F, but rather A+ vs A++. That doesn't mean that there aren't meaningful differences (see Is there any significant difference between Nikon and Canon? and What do Pentax and Sigma DSLRs offer that differs from Canon and Nikon? if you want to explore that further), but generally it's a matter of working in a slightly different way, not better or worse.
As you get more advanced, you may find you have particular needs that one brand may fit more than another. You'll hear a lot about how your initial choice "locks" you into a system, but that's only true if you start with a big investment. If you're just at the entry level, it's really not that hard to revisit your decision later. More important is to get a camera and get shooting rather than shopping.
Lenses
Don't overbuy at first. You only need one lens, and not necessarily a super-zoom. You just need something that fits what you want to do. For basic landscapes, the "kit" zoom which comes with most cameras should do, especially if you get a decent tripod. For macro, you'll probably also eventually want a dedicated lens, but you can get amazing results with reversing rings for cheap.
Once you know more of what you're doing, you'll naturally know which lenses you want or need. For some people, having a whole arsenal of choices important, but in general, the advantage of interchangeable lenses is that we can each find what fits us best. (Read this.)
Easiness
I strongly agree with Russell on this: surface-level easiness is only something you want if you're only going to use the camera once in a great while, and in that case I'd question whether you should buy a DSLR at all. Often, features which seem easy at first are in the way (useless at best, but worse annoying), and things which have a learning curve actually make day-to-day use much easier. See Are there disadvantages to a prosumer camera for a beginner, aside from cost? for more on this.
