Im gonna give it a shot and try to answer the questions as best as I can here from what I know of this case.....

1. In 1995 I don't believe cell phones were the norm as much as they are today(I didn't have one myself until 1998) and  we used them much more infrequently as there weren't many standard data plans, etc. and paid by the minute or had a small number of minutes to use for the month before being charged per...Amy Kuns never said she called Jodi's cellphone, but called her home and that Jodi answered the phone in a groggy fashion, as if being woken from sleep...

2/3. If Jodi had those items in a bag she slung across her shoulders and then  she struggled and/or was dragged, those things could have been dispersed, then finally dropped between her car and her abductor's vehicle.. The bent key could have been dropped immediately, perhaps having been bent and yanked suddenly as Jodi was grabbed by her abductor as she put the key in the lock...It was said she had a keyless entry remote so I find it mystifying she was even using the key to unlock the door...I wonder if its possible that Jodi had made it into the car or at least put the key into the ignition as she was grabbed and perhaps dragged out of the car...But there has never been any evidence of this as she still had all the items on her person when she was abducted...

4. The whole toilet seat being up scenario is a red herring I think...I know myself I would never lift the seat up to vomit in the toilet. Why, exactly?  And if ur gonna get sick like that, who really has the presence of mind to lift the seat up, unless of course she decided to clean it thoroughly afterward...If she was running so late, would she have had the time? There is at least the possibility of a man having been in her apt the night before or that morning...But cops dropped the ball when they didn't thoroughly scour her apt, concentrating mostly on the abduction scene in the parking lot...DNA, fingerprints,etc.,found in her apt could have been helpful...I have also read that one of the responding(male) officers may have used her bathroom and left the seat up, obviously not treating her apt as a crime scene....

5. I don't remember if a purse was found...Perhaps her earrings were just thrown in the same bag with all other necessary items in a smaller compartment and just fell out too...Or perhaps she was wearing earrings without backs that could have come off in the struggle ...

6. Im up @ 4am when I have to work...Im a waitress and I need to be in by 5;30...I need time to wake up and get ready...Yes there are many people who need to get up early...and others who are up early because they cant sleep...To me this  question is moot...Jodi's screams may have woken one or two people up also...When u are jolted from sleep like that you are not always thinking rationally or clearly...There also was a campground right next door to Jodi's apt building and the holiday weekend was just over and there had been some sort of Renaissance rennacting group or whatever that had been there over the weekend...People who heard screams thought it could possibly be kids or whatever in the campground....Then theres always the excuse that people don't want to get involved in things and most likely didn't take the screams seriously enough to warrant a 911 phonecall...

From what I remember the person who saw the van was not a resident of the apts and saw it from the vantage of the street...And presumably before the abduction as he never said he saw anyone or heard anything....Just the van..So you cant combine that with the people who heard the screams but did not see a van(or anything else)..
