You have to be joking. First off, the process version has to do with how LR/ACR is able to process the image. The 2012 process version is leagues beyond 2010. The camera profile is LR's recreation of the the in-camera Picture Styles. This is 100% optional, and in most cases Adobe Standard great. What camera settings are you wanting it to import? You know, you can create your own develop presets to apply to the images upon import.
As to the OP's question about LR loading the image, have you ever used LR with an image from another camera? Are you rendering 1:1 on import or standard or minimal? As stated before, your camera isn't showing the full res jpeg. If you aren't rendering 1:1 on import, LR has to render the image when viewing to fit screen or more longer for the 1:1 preview.
I'm not trying to turn this into a LR help section, but I know LR ignores camera settings of things like Picture Style, HTP, Auto Lighting Optimizer, etc. I'm sure ACR does too. Plus, if you set your camera to a certain Kelvin setting, take the picture, import it into LR, the temp in LR will be totally different. I just haven't mastered how to fix this without completely starting over on something I already did when I took the photo, ie blown highlights in LR and not on camera. I'm not joking either, this is a well-known issue. It auto-recovers highlights and it also does this with whites. There is a difference obviously between 2012 and 2010.
As a final note, I'm not saying this is out of the oridinary. It's not good, but it's probably normal and something you must master and get good at, which I have NOT done yet. Like I said in an earlier thread, I am better at PS. For some reason it just clicks with me better. Would I love to do all my processing in LR? Of course, it's way cheaper.

Yes, certainly going to try to learn to do this.
