Your examples are way too small (and all without EXIF info) in order to give them them a proper examination. The palm tree example though is certainly a soft focus. The best thing to do is provide us with 100% crops of areas with the most detail.
In regards to the palm tree photo, the questions to ask are:
1. How does your lens quality compared to the Nikon's lens? In most cases, Nikon lens (in particular Nikor lenses) are almost always superior to Pentax lenses (I'm sure this is going to get me into trouble but you can't argue with facts).
2. Is it a soft focus problem due to FF or BF issue?
3. You simply didn't focus properly (you did say that you used manual settings).
4. Aperture was fully opened which greatly decreases depth of field; should you have stopped down a bit more? Enough to have better focus on your subject yet keep the background blurred.
5. It's too small of a sample to know for certain but perhaps the shutter speed was too slow and you have introduced a slight blur due to movement.
Originally posted by wingk1314 The outdoor night picture shows the same thing. Too warm. She was under yellowy white light. But I'd say it was more close to being white.
It doesn't matter what your eyes see. The camera's sensor will often see color balance different from your eyes. Outdoor lights come in all different types of technologies such as high pressure sodium and lights like this have very specific and narrow spectral patterns, which might fool your camera's AWB setting. That is why shooting in RAW and doing post processing is always the best way to ensure appropriate color balance.

Actually, that may not be the right approach.
Like film skills, digital photography skills don't begin and end at the camera. It might be wise to take a holistic approach when building your photography skills. It starts at the idea, the composition, the camera, the post processing with the computer (Adobe Lightroom is an excellent tool used by amateurs and pros alike), and finally the final output (screen or print). In some ways, all of these skills share a symbiotic relationship with each other.
Back in my film days, I often stated that I would fix a situation in the darkroom. Of course, then it was much more work to correct problems, compared to now.
Originally posted by wingk1314 Regarding monitors, It shouldn't be the case since I have a mac and PC as well as 3 seperate LCD monitors at home. Yes, there are differences between the photo's colors on each display. But overall the same issues are noticable.
Agreed! LCD monitors don't suffer from focus issues like the old CRT monitors.
Originally posted by wingk1314 Regarding my friend's nikon's photos, unfortunately I don't have her photos on me currently, but I'll see if I can get a hold of them. We both went out one day and took some photos together and then uploaded our photos onto her laptop. There was a clear difference in color reproduction/sharpness and contrast.
Oddly enough, I rememebr she mentioned something about ACR or a setting like that that enhances the contrast/sharpness. That's probably a reason why there was differences in those areas between our photos.
ACR stands for Adobe Camera RAW... which is a plug in (for Lightroom/Photoshop) which that supports many cameras when photographing in RAW. The latest plug in supports the Pentax RAW format as well. See this link:
Adobe - Adobe Photoshop CS4: Digital camera raw file support
Anyhow, you are dealing with a whole range of differences. Namely, each camera's settings and and especially the lenses. But equivalent camera settings will almost always negate the differences, so that leaves the lenses to compare.
