I completely eccho Mr Dreadnought's views. I also work only in 1/700, but would suggest that you start with flexing your muscles in a small 1/350 build - and the Trumpeter England or Tamiya Fletcher are the right places to start. Save PE for the second build, after you're comfy with doing a ship in recent memory - like you say, skills go away after some on and off time.
If you want to flex another muscle on this first build, then maybe you might want to consider building your DD or DE as a sister with an interesting camouflage schme, starting from Measure 22 (http://www.shipcamouflage.com/measure_22.htm) or working up to something like a challenging pattern with colors like Measure 31 (http://www.shipcamouflage.com/measure_31.htm)
Note: a table here (http://www.shipcamouflage.com/fletcher_class.htm) tells you what measure (color set) is used with a particular pattern (visual shape) on individual ships during their careers. Somepace on the web there is a set of 2 dimensional pattterns for thouse schemes.
At any rate, this camouflage business is an integral part of ship modeling, as much as PE, just like with armor, and is a skill you can develop in parallel with PE, starting easy and working up.
Welcome aboard!
