They are all good cameras. Read the reviews on this site first, then go to a store and see which one you like best..
All good cameras..
It's most important you are comfortable using and holding and viewing through a DSLR, so try and see these camera in shops. Reviews often pay particular attention to this area for this reason..
In broad terms the D40 and K100D use the same sensor. The K100D has IS, the D40 shoots a longer continuous sequence, and I doubt either would disappoint..
The E410 is the smallest and lightest, which sounds nice unless you don't find it comfortable to use ( like me ).. The 400D I personally dislike, as I disliked the 350D, because I find it too small ( although this shows you how personal the choice is, as they are all very close in size and shape, apart from the Oly )..
Also have a look at the K10D, the K100D's bigger brother, which is well priced at the moment..
In terms of image quality you would not be able to tell one from another at any normal print size, maybe up and including to A3..

I agree, all are great cameras it just has to deal with personal preference. I do stress though that with the great deal on Pentax K100D Super and you can pick up a great low light lens to use indoors 50mm f1.4. But you should try to layout of list of what you are looking for, then find one that feels good in your hands like mentioned..
Nikon D40 or PentaxK100D or Olympus E410 or CanonEOS400D.
All good cameras. Get the one that feels best in YOUR hands. Actually take pix with them in the stores. Get the one that is simple to use..
As already mentioned, the Pentax K10D is availabel with a $100 rebate now. That makes it a real bargain. It is much bigger than the other 4 and heavier. Some people like that (I do). It is sealed..
I have Photoshop on my computer and would like to learn how to usethis and improve my skill with a camera..
Lurk on the Retouching Forum here on dpr. That will teach you how to use PS..

This link has both Olympus 410 and 510 reviews, get the 510 the anti-vibration system is very good and it's nice to get good quality without a tripod and even better with a tripod. The 410 doesn't have it, read them both and read both of the reviews here and take a good look at the 510 sample photos with the noise filter off. http://www.wrotniak.net/photo/oly-e/e510-rev.htmlTim.
PS the 510 also has a good dust removal system I have yet to take a photo with dust on it, I'm really impressed with this camera. Oh, look at the battery size also...
