Is it a big problem just to start bash once you've logged in?
I had it like you untill I discovered just how cool csh manage your
command history: Type the first letter and it will only go trough
commands with that letter, type two ... yeah you guessed right.
But I do like that bash shows me the options when autocomplete does not
have a unique completion.
If it really annoys you, you can go through scripting the login such
that it will start bash if it exists and otherwise csh/sh whatever.
It is doable, I had my login create a time stamp file and open an editor
on logout to produce a cvs-sort-of-like history - why where you root?

Have your ports tree writable by the staff/administrator group. When
privileges needs to be elevated you are prompted for a password.

You don't, just as you don't send email as root. root email should be
forwarded to members of the wheel group, and a local copy only kept for
reading when everything is down.
Alternatively, with cyrus-imap you can share a common mail-box to
specific users. I like this solution, as I can see if someone else had
read the mail and hence assume they also took care of any problems.
It is my experience that if mail is not forwarded the responsible will
tend to forget to read it and problems may go unnoticed for days.

rsyncing what? do you allow remote root login on your servers? I don't
have anything that needs rsync by root, but even when I did, it was a
Certainly, there are things that need to be done as root, but these are
typically single commands.
You don't need a permanent root shell. If you have a major task to do as
root, go ahead startup bash - what's the big problem?
