An iPad app called Notability meets most, if not all, of your  
requirements.  Page transitions might be
a bit too clumsy for you, but that's probably the main failure.

To import a PDF into the app, store it first in DropBox from your  
computer, whence you can download it
directly into Notability.  You can write on PDF pages, or on blank pages  
the app create and will store
on DropBox as PDFs.  Use one of Adonit's JotPro styli (about $20) instead  
of an Apple pen (~$100).
[If the stylus' writing becomes flaky, put a drop of conducting lubricant  
in the ball joint near the tip.]

If you want, you can altogether give up using a black (white) board and  
project lecturenotes you hand
write in class (or your annotated LaTex output) in Notability.  Then you  
can upload them directly to
DropBox as PDFs on---which you can make available on the Web.  (DropBox  
isn't very suitable for the
latter:  DropBox allows you to make files Web-accessible, but it imposes  
download limits that a class
of any size will quickly bump into.)
