Agree with tom re. CRP1 v CRP5 - no point having both, the CRP5 does everything you need. (But, for the benefit of others reading this thread who aren't planning on going commercial, there's no point buying a CRP5 if you're not going to do a CPL.) I have both - I bought a CRP1 before I decided to do my ATPLs, then discovered I need a CRP5. I now keep my CRP5 on my desk, to use when studying, and my CRP1 in my flight case, to use when flying - it's nice to have a "spare" so to speak, but not essential at all.
I would stay away from computers at this stage, especially if you're planning on getting an ATPL. You'll need to be very good at using the CRP5 for the ATPL flight planning exam - and any practice you can get is good practice! Nothing wrong with using software once you've finished the exams, though - so long as you trust the software, that is.
