Thanks much! Yes, I've had my Sony A700 for years and really like it. I have been considering swapping out for an A77 mainly due to the video capability - I've seen some awesome video work using SLR's recently and pretty intrigued.
I usually shoot the G-series 70-300mm if I am going to try and get some decently crisp dog or wildlife shots:
I shoot my G-series 16-105mm for landscapes or get some strange perspectives:
Sometimes I'll shoot landscapes with the 70-300mm but you gotta get a little crafty - took this as two shots without lowering the camera focusing on the tree then on the moon (or the moon then the tree can't remember) then combined 'em:
One thing I've done that you might enjoy doing Don is renting lenses from
http://www.LensRentals.com For a decent price you can rent some pretty phenomenal (and scary expensive!) equipment - they make the whole process super easy and you can try out that $12,000 500mm f2.8 prime before you buy it.

Last year I rented a Sony 300mm f/2.8, added a 1.4x teleconverter (giving me an effective 420mm ~f/4 setup) with a heavy duty carbon fiber tripod for 3 days for about $300-400 for a trip to Yellowstone. Going to do the same thing again here in a few weeks.
