There are plenty;

GPass, KWallet, KeePass (previously mentioned), and probably more even...  

I haven't used GPass and KeePass before, but I have good luck with KWallet (though I'm a KDE user).  Chromium has KWallet support and there's a firefox add-on.  

I'd recommend reading through their features and picking something that makes sense.  KeePass may interest you with its cross platform support, which could allow you to maintain one password system between operating systems. 

Any open source alternative to Roboform
Being a beginner, I can't see why I must choose an 80-200 over an 18-200. Are there scenarios where an 80-200 would be preferable over an 18-200?

I will be buying a D7000 soon and am looking at these:


AF Zoom-NIKKOR 80-200mm f/2.8D ED
AF-S DX NIKKOR 18-200mm f/3.5-5.6G ED VR II


but similar considerations would apply to other brands as well.
