Great photo! Welcome! Especially the kids!
This is normally where I recommend Premium membership so you can see all the caches, AND so you can plug in your location so Ground Speak will send you a weekly newsletter about local events, and geocaches, and helpful hints. There's many more benefits, but information and connections are usually most valuable to you early IMHO.
There's some great caching all around you, the Katy area is overflowing with great geocachers and hides.
I'd immediately say go to some events, but many times they are at restaurants and you'd probably go broke based on that photo! Seriously, events are terrific for connecting and gleaning info. Highly recommended. There's also the "Mash Ups" section on this board when you know you'll be wanting to go out and cache a general area. Just post your intentions and somebody may pipe up and join you. If they are experienced it will be useful to you and generally improve your "Found It" logs and help prevent kids from getting bored. Like fishing, the kids respond to results regularly, and take Did Not Find's even worse than Texas Writer!
Why am I all sweatty and late? Umm...
