Regarding Regex:
Can all of its functions be replicated by regular expression commands to

Yes, but I'd consider it a cheesy hack at best. It's clearly possible,
but incredibly expensive even compared to a normal scripting addition,
let alone something built in. For example:
set s to "foo foo foo"
do shell script "echo -n '" & s & "' | sed -e 's/foo/bar/g'"
--> "bar bar bar"
That worked, but it had to call a scripting addition, spawn three new
processes, and do file I/O between them all. Trust me, you don't want
to do this too often -- doing it just 100 times on my machine took 12
seconds.
