If you are talking about Pentax lenses that's good as you won't get any compatitbility issues. Other makes should be examined carefully to ensure there are no extra bits (such as the extra pin on Ricoh K mount lenses) that could cause a problem.
1. Use the Pentax Adapter K for your screw mount lenses and then you will still get infinity focusing. You can expose manually or using aperture priority without too much hassle.
2. The focal length does not change (a 50mm lens is always a 50mm lens) but the smaller sensor means only the centre of the field of view is used. So the effect of using a 50mm will be similar to using a 75mm lens on a film camera. The DOF will be as for a 50mm lens.
3. Manual focusing may not be a problem, depending on your eyesight. I find it OK, others need to change the focusing screen. I'd just see how you get on. The essential thing is to adjust the eyepiece dioptre using a blank even toned scene - sdjust till the guide lines in the viewfinder are at their sharpest. When making this adjustment it is best if you do not have a scene that can be focused on (blank sky is good) as the eye adapts very quickly and can distort the result.
4. Wishfull thinking? Of course... But the new K-m is not far off.

Didn't you resize when you uploaded to Photobucket to make the image 800 pixels wide for the forum? In Photoshop just go to Image>Image Size and put in the number of pixels you want as, say, 1000 on the longest side. That's it, just save it as a JPEG and you're ready to upload.

If you can upload a picture to Photobucket and link it into the forum then the competition process will be a doddle!
Good luck with your entry.

Sometimes there are incompatibilities. Fuji cameras were particularly off in this respect.
