Loren,
First congratulations for the K-7. You cannot get wrong with it, but it is worthwhile to read the instruction manual because the camera has many very useful functions.
I agree with lowspark86 that the 18-55WR and 50-200WR DA kit set is a worthwhile zoom lens set to consider.
The alternative 18-135WR is also a nice option to have a more compact system and limit/reduce lens swapping. Personally I would favor the 18-135WR over the WR kit lenses.
I have a K-7 that I use often outdoor in harsch conditons, and I went on a different way. I chose the DA18-250mm as my all-around lens and I complemented it by fast prime lens (Voigtlander Nokton 58mm f1.4).
The DA18-250mm and its sibbling Tamron 18-250mm is a superb lens in its own category, with all limitations of such a zoom, and all the versability of the huge focal length range. It is well-liked among Pentaxians and the envy of many Canikon users. The 18-250mm is not WR, but the lens is very sturdy. It does not have OS not HSM, and that is an advantage in solidity. See for example:
K-7 and Steve Kroeger climb Aconcagua (6962m); yes the lens on the K-7 is the DA18-250mm!!!
The main weakness is the 18-250mm is its low light capability. Hence I complemented the 18-250 by a large aperture lens (f1.4) that makes a huge difference at dusk, sunset, sunrise. The Nokton 58mm is a very sturdy lens that is basically WR 'without the badge'. The fast prime is small and can fit easily in my jacket pocket. And I have a small top-loader bag for the K-7 + DA18-250mm + charger + cables.
In practice, I use the 18-250mm nearly 80% of the time, and the fast prime Nokton 58mm in low-light conditions primarily.
I hope that the experience will help.
