The right SLR for the job & Megapixels vs Lens

[Lynnzora]

Also what do you think about the 14 mp Pentax... Who has used it? What do you think about its quality for what I'm trying to do? Is it easy to find affordable lenses to go with it? Maybe I'm just a tad uninformed but it's brand that I haven't heard of... That's why I'm questioning it's quality compared to others. I want the best for what I have to spend.

Those are all great cameras. Many professionals use them all. You'll probably hear the most regarding the canon and nikon because of their (large) market share, but the pentax is perfectly capable as well. You won't be making a bad choice, regardless of which you choose. Make sure to get at least one good lens in the focal length you want for portraits - something in the 70-150mm range would be ideal.
