What's a decent CF card for Nikon D3?

I have recently upgraded from a Nikon D300 to a D3. I was wondering what sort of CF cards I should get, so I can get speedy performance without breaking the bank.
I currently have a few 4gb Sandisk Ultra II's (15mb/s), though I doubt these are up to it. I'm not sure how big the D3 buffer is, off hand.

I do a lot of birding, so I usually use a fast frame rate. 6-8 fps.

Digital camera focuses-out small far away objects?

My digital camera focuses away small objects like birds when against a mono-colored background (blue sky, grey lake water) as if they were blemishes. How do I adjust the settings to stop it from focusing-out the object I zoomed in on? I can usually see the bird up to a point as I'm zooming, but if I zoom the whole way (my camera goes up to 21x) it goes out of focus or blurs or I don't know what (and usually a few steps back in focus, the bird is too small to see, period). I frequently take bird pictures and often can't get close to them, and this problem happens all the time. I can't find the answer in my manual. The brand is Nikon.It doesn't have add-on lenses.

How to use a old film SLR lens on a DSLR?

Recently I bought a Canon T4i, and I have the kit 18-55mm lens. Before I bought this, I had a old Nikon N50 (film). I realize that a Nikon lens won't work on a Canon body, but I just saw this adapter thing for a Nikon to Canon lens.So my question is will my Tamron 28-200mm Nikon lens work on my Canon T4i, and if so, what adapter do I need.
