I think it's a great instrument. It's the reason that my bass guitar is currently collecting dust.
Now, I agree with getting a guitar custom-made by a luthier, but if you can't afford that, look for a LaPatrie guitar. These guitars compete with others that are double their price. And when you get a guitar, watch out when it comes to temperature/humidity damage. Mine recently got cracked because I neglected this.
About technique, you're going to find a lot of spirited discussions about nails. I have a handy book called "Pumping Nylon" by Scott Tennant that has fantastic tips for this and other technique issues.
As for a specific technique hurdle, I had trouble when it came to string crossings because on guitar, you don't follow through when you have to strike the lower adjacent string (I call it "raking through", though I don't know what others call it) Learn to shake off this habit when you move on to guitar. And don't worry, your brain will differentiate between this and bass, so you won't get your technique muddled when you're playing bass.
As for guitarists...
If you haven't heard about Andres Segovia yet, get ready to hear his name over and over again. I also like to listen to Roland Dyens, John Williams (not the film composer), Julian Bream, and a whole bunch of others.
Now, here's a real helpful website when it comes to getting some free sheet music:
