Your leg strength and cardiovascular endurance from running will help a lot. But cycling uses some different muscles from running so you can expect some soreness, especially in the quads, glutes, and a sore "saddle" (the area just south of the glutes). Before I got into cycling, I used to run marathons - when I was in marathon condition but rarely cycling, a 30 mile ride was no big deal but a 40 mile ride left me with aches and pains. Obviously this varies from person to person - you won't know your pain threshold until you get out and ride a few times. Many of the organized Katy Trail tours have 50-60 mile days, but a full tour requires some training.
Unless you only plan to ride a couple of times a year, don't buy a bike from a "big box" sporting goods store or Walmart type place. You'll want to go to a bike shop where they know how to help you find a bike that fits your body. Fit is important (they say Lance can tell if his seat is off by a millimeter) - a poorly fitted bike could leave you with mysterious pains that keep coming back each time you ride.
Your own budget is the biggest factor in what to spend. Most bike shops will let you try out several models on their parking lot, and you'll quickly feel the difference between a $300 bike and a $1000 bike. And of course how often you plan to ride - if you're only riding a few times a year then you really don't need an expensive bike. If you just want the occasional ride on the Katy Trail, you might be better off just renting. Sorry I can't give a more precise answer, but it's something each person must answer for him/herself after visiting a bike shop or two.
If you do buy a bike, don't forget to reserve some of your cash for accessories: helmet, car rack, computer (odometer), lock, bags/panniers.
