National Geographic is about the best there is and sometimes they do photographer interviews as well.
Otherwise the rest of the market are quite poor in content - I would better recommend a few good books along with time on the internet and you can gather up pretty much all and more info than you can from many of the magazines - many of which are very very entry level in their approach - expecting where it comes to editing where they all expect you to have photoshop CS5

and few (if any?) make any help or use if you are using something more suited to a beginner like elemets.
The Digital Photographers Handbook by Scot Kelby is where I started - its a simple book that gives you basic settings and starting points for a variety of situations and conditions as well as giving general gear advice for a range of interests. It's not trying to go into much depth, but it gives you that all important starting point.
Understanding Exposure by Bryan Peterson is the natural build on book from the other - this goes into more detail about using and controlling exposures and the content it covers will leave you in good standing for a long time.
From there you can try some of the other highstreet books and these break into two kinds - the informative and the overrated picture book. Now there is nothing wrong with picture books, but if you are after info they are very poor choices and will only go over the basic starting points in brief.
If you've an interest in nature/macro/landscape John Shaw has published a range of books (some only on the second hand market now) that cover these aspects and each is well written and well worth reading - even if the gear talks are a little older, the same principles for film still apply to digital photography.
Further if you go into more nature work I strongly recomend The Wildlife Photographers Field Manual by Joe McDonald - there is a lot of good detailed info packed into this little book
