Random lengh of psd files imported in After

Hey! I've had the same issue using artboards in photoshop that is because Ps changes the overall size of the "canvas" and shows content only around where the artboards bounds are. If this is the problem you can simply click Files>Export>Artboards to files and change the settings to export PSD's that will export every artboard as it's own PSD file with no artboards meaning the canvas size should be correct so Ae will be able to interpret it as it should

Just to reiterate:

When importing a Photoshop document or an Illustrator document as a Composition, the resulting Composition Name, Width, Height, and Pixel Aspect Ratio is taken from the document.

Most other Composition Settings (namely Frame Rate, Resolution, and Duration) are taken from the current Composition Settings.  That is, whatever we would see if we start a new Composition from scratch without importing a PS or AI as Comp is what we'll get when we do.

Start Timecode will default to 0:00:00:00 and Background Color will default to black.

I agree that being able to set Frame Rate and Duration at the time of import would be helpful.  You can vote for this feature here: https://adobe-video.uservoice.com/forums/911311-after-effects/suggestions/35107474-import-psd-as-composition-duration

Without any specific info about your PSDs, your footage interpretation and other settings we can't tell you much. Importing a static image shoudl definitely not produce random results and simply use the default still duration set in the preferences, but you really haven't provided any "hard" information despite your lengthy explanation. Screenshots would certainly help and might reveal the issue.
