Does anyone have idea about how to attach an AC line to a PCB board?<<
Any good, solid, well-isolated soldered connection is fine. Common sense
stuff!

I have a transformer that is actually on the board itself. Is this a
good/bad idea?<<
Very common practice. Perfectly fine, if done properly.

Do I basically drill a whole and stick the wire through the hole and solder
it one?<<
That would be OK in situations where the board will be mounted, and the
AC-lines not flexed often, as they might be if an "AC line-cord" is used here.


Should any grounded part of the board be connected to the
netural line on the AC?<<
NO!

Should there is some kind of connection such as through a transient
supressor? Any help is appreciated. <<
What KIND of connection do you mean, here? Use of a transient suppressor is
fine. That's what they are FOR. But not necessary in every case. Depends
on what you are doing! Again, "common sense" is a serious factor, here!

Also, should there be any type of noise supression on the AC side of the
board? What about grounding planes on the AC side? Thanks!<<
see the previous response.

Be careful! Lotsa luck! Jan Rowland, Been there; DONE that.
