Opportunity to purchase New Gear

[ROA44]

The Last few months haven't allowed for much time to get out with the camera, due to my sisters illness and even less since her passing away a few weeks ago, but I hope that as things get sorted out I'll soon be able to start taking photos and also get to spend some time reading S/Kelbys' L/r 4 learning L/room.

Although this will now allow me the opportunity at purchasing some new gear, but now without the same excitement & enjoyment.
EG. Flash, filters and the more difficult choice lenses.

Hence the post. I have the D5000 which I have been quite happy with and at this point I'm not sure I'll worry about upgrading to F/F or as nice as it might be the new D7100 does look tempting.

The big question is lenses. I use mainly the Sigma 120-400 (probably sell) and occasionally the 35mm 1.8 and have the 2 kit lenses which I hardly touch. I'm considering.

1. Portait Lens, Nikkor AF-S 85mm f/1.8G or 105mmf/ 2.8.

2. Wildlife lens, Sigma 150-500mm or Nikkor AF-S 200f/2, 70-200 f/2.8 + T/C

3. general purpose zoom eg f/2.8 ? for when just going out for the day still looking at options

4. thinking about wide angle lens might hold off for a bit ?????

Just starting to look at other brand options.

So these are my current thoughts and want to set up for the long term with out having to re-purchase others unless to move into a dedicated field but not looking to do so at this point, but if I did buy a F/F have I strictly speaking cut my self short or will they still perform well.

Thank you for your thoughts
