K-30 +18-55mm & 50-200mm for $600
Yes, especially if they're both WR.
Now, bear in mind these are 'kit' lenses, with all the limitations you would expect from a starter kit. Slow maximum aperture (especially at longer focal lengths), average to slightly better-than-average image quality and low resale value (this value would be vastly improved if they're WR).
If you don't intend to pixel-peep or make huge blow-ups, don't normally shoot in low light conditions (the K-30's high-ISO performance will help here) and don't feel you'll want an upgrade too soon, you'll effectively have the 18-200mm range covered with 2 lenses, plus a very good body.
