After CRP, I'd recommend that you focus on GS (for Innovation) and WVR (for Careful Synthesis II). Those two skills will be very helpful for leveling the rest to 50. You're going to want to get all the skills, eventually, as they will all have their uses.
Just make sure to keep your eyes open for profitable opportunities, along your journey. There's little point in rushing to the top, when really the only thing waiting for you is loads of competition.
