There are a lot of different skis out there and a lot of different types of skiing. To make matters even more confusing, there are a lot of different terms used. I personally like to classify it like so:
1) Groomed
2) Ungroomed Road Skiing
3) Touring, or Light Back Country (basically rolling hills)
4) Ski Mountaineering
Unfortunately, most of the stuff you read is geared towards the opposite ends of the spectrum. You can find magazines that mainly focus on groomed Nordic skiing (including articles about racing). You can also find magazines that cover extreme ski mountaineering (which are really fun to look at, even if you would never go there). There isn't a lot of information about the other type of skiing. Fortunately, the stuff in the middle is a lot of fun, and much cheaper.
What you want, basically, is a good compromise setup. Like any compromise, you may find that you gravitate towards several pairs of skis (and boots) over time. Personally, I have the following setup:
1) Very light skinny skis for the tracks. I use regular (SNS) Nordic bindings.
2) Fischer Inbound Crown skis, with the same boots. The Inbound Crown have a fair amount of sidecut (10 mm) but no metal edge. I recommend this design for most conditions. It is very light, but the sidecut allows you to maneuver on a wide variety of terrain. They are also a bit wider than many Nordic skis (you can go even wider with Outbound Crown or other models). This allows you to break trail fairly well as well handle deep snow. I've used these skis on terrain where most people use BC gear or much heavier, bulkier gear (Telemark, AT, etc.).
3) Atomic Rainier with backcountry bindings and boots. These skis have metal edges. I've used this gear on more difficult terrain. The metal edges are really nice when the snow gets crusty. On the other hand, they are unnecessary if the snow is nice. Unfortunately, you just can't get skis with this much sidecut (or more) without getting metal edges. These skis are also fairly good in the tracks. Quite often, you will spend a certain amount of time in the tracks, and then off trail. This is fairly popular for that, especially for folks that don't want to go with anything lighter (people have been known to put telemark bindings on Rainier's or similar skis).
I don't want to imply that those particular skis are the best skis. I think they are very good, but there are a lot of other good ones out there. More importantly, I would try to get skis with similar characteristics. Basically, I would start with category 2 or 3. Personally, I would start with category 2, and just try and avoid skiing icy conditions (which means that you may decide to snowshoe on those days). It is, I think the cheapest overall setup to get. I think it is very important to get good sidecut. You can find a lot of skis that don't have metal edges (and a few that do) that have 5 mm or less sidecut. I think this doesn't make sense. At that point, you may as well get skis in category 1. Likewise, it makes sense to get skis in the third category that are a definite step up from the second. That way, you can cover a wide variety of terrain.
I might also add that there is a 4, 5 and 6 (or more) to this grouping, but I don't know that much about it. These are for folks that want more control. They tend to ski tougher terrain or in tougher conditions. They also tend to do more skiing that involves using skins to go up steep terrain, and then making really pretty telemark turns going down. You can use this heavier gear for the other type of skiing, it is just more expensive and (generally) more tiring. You can use the lighter stuff for steeper skiing, you will just fall down more (unless you are a really good skier).
Unless you live in area that is always cold, I would get waxless skis (the skis above are waxless). It is just a lot less hassle, even though it is a bit slower. I would also get a pair of skins or kickers. I've used them with my Inbound crowns quite a bit as well as my Rainiers. Sometimes the snow conditions just make it difficult to go uphill without them.
