The Regex Coach allows you to write regular expressions and
test them against a string to see if they're working - it's excellent.

I couldn't find anything particularly useful about how to alter MySQL
table structure in a situation where replication was being performed so
I pretty much had to try something out to see if it worked.

What I found was that MySQL was remarkably clever at replicating
changes through from one database to another. I don’t know whether just
running a straight ‘ALTER TABLE’ command would work or not but I took
the added precaution of running a ‘STOP SLAVE’ command (on the slave)
first. Then, once the new column had been added to the master, running
‘START SLAVE’ kicked it off and the database automatically picked up
where it had left off by propagating the table alteration and then
updating the data.
