Yes, they should be attached to the GET request.
There needs to be one for each string.
The matched data are saved in variables (which can be anything).

Functions are used anywhere that variables can be used.
e.g. on the Sampler to provide a value for a parameter.

Not sure I understand this, but it sounds as though the URL for the
postback request has changed. Unless this varies for each postback,
this is a one-time fix to the postback sampler.

This is where the function comes in - it would translate a$b$c to
a.b.c (or whatever).

This is not the same transformation as $ -> . above, but can be done.
If you know javascript, you could use the Javascript function instead
of teh BeanShell function.
