[Orgmode] Dates in agenda

[Richard G Riley]

Is it possible to turn off dates being shown for repeated tasks in the
agenda?

e.g I do not want to see the original creation date here on the pub quiz
entry:

,----
| Tuesday    1 April 2008
|   Shamrock:   21:30...... Pub Quiz <2008-03-25 +1w>
|   Diary:      April Fools' Day
`----

Also, lets say I have an item with some notes e.g

,----
| ** [2008-03-14 Fri 13:22] semantic completion check for eriks reply 
:@home:Online:emacs:
|    SCHEDULED: <2008-03-17 Mon 14:00>
|    <2008-03-17 Mon 14:00> Dont forget to remove debug code
|        removed all message() calls.

I want to add a note without changing TODO state. Is the quickest way
just to move to the end hit "C-c ." then move to next line and type or
is there some sort of "add note" function?

Currently I insert the timestamp manually with "C-c ." hit return and
then TAB to the first column to align with the note aboves timestamp. It would 
be
nice if hitting return automatically did move to the typing column - is
there some more generic emacs way or org way to turn this on?
