If that's the case, then maybe Walter didn't
actually accompany Michael there. Ergo... he's still in this timeline (time paradox thus averted) and was therefore able to send the letter to Peter with the white tulip though the U.S. mail. Somebody
had to do it, right? Because, if the U.S. mail has through-time next-day delivery, then 45 cents for a first class letter really is
the greatest deal in the world!
The last videotape and Peter's conversation with Walter explained both things. The videotape is of Walter from some point in the past saying that he had sent Peter a letter... and that when he got it he might be confused... but that he would understand now from the videotape.. At the time, Walter assumed he was going to be able to build the machine then and take care of things... instead, he spent 20 years in amber. One assumes that in the pre-reset timeline, the tulip was still mailed but Peter never got it because he too was in amber.
The tulip-mailing works in the same way it worked when "Robocop" did it... "Robocop" mailed the tulip to Walter before his last time jump... so Walter got a tulip in the mail that he didn't know why... Similarly, Walter here mails a letter in the past before being ambered, before the time-jump, and after the time-jump Peter in the past gets that tulip.
The serum was explained by Walter in that conversation after the video... he tells Peter he was already injected but had prepared another serum just in case it was needed.

One other thing I feel I am just not very smart about is how does showing the scientists a "better version" of Observers keep them from invading? I guess I lost track of why they invaded in the first place ;
See my earlier post for a likely plausible explanation: http://www.avsforum.com/t/1063404/fringe-on-fox-hd/6250_50#post_22849870
Walter helping to preserve the past by orchestrating the future is the only way that makes sense for all of the universe's past not to be unraveled. There was even foreshadowing because Walter in-episode stated that he would not "change a thing" with regards to how his life had progressed and the "bonus time" he had with Peter. Resetting the timeline would in fact be Walter's chance to rewrite history... but he presumably chose to accept the bad with the good AND instruct the future more benevolent Observers on how to preserve the past that led to them.
As to "the plan"... We were told two key things about the Observers.. First, that they had ruined their planet and wanted to come back and take "ours"... Second, that the future of humanity had evolved where emotions were sacrificed to achieve intellect... and along with that went morals and other things... so these emotionless Observers thought it perfectly fine to do what they were doing.
So... "the plan"... "Michael" proved to be more powerful and apparently more potentially intelligent than the Observers... and more importantly, he was so because of his emotions being intact... So, the scientists in the semi-future would see him as a better evolution, smarter and stronger... and at the same time he would keep his emotions... so presumably that future race would be more capable of right from wrong AND might be enough smarter so as to save their planet rather than have destroyed it. Or at least the theory I'm going with.
