When you have outlets connected in a nib file, the very loading of the nib
file initializes all the objects for you.
So if you are making a self contained module..your init method call the
appropriate method (loadNibNamed) and makes your current class the owner.
The method also makes your class a delegate, so that you can be told when
the interface items are fully loaded, initialized and outlets/actions connected.
This is where awakeFromNib comes into place..it tells you when the NIB
is fully loaded, and ready for use.

Yes for the first case of pulldownmenus you need to set the menu outlet
of the table or view.
For formatting you should be able to use the NSNumberFormatter or NSDateFormatter
both which you can drag and drop into the appropriate table in Interface Builder..
or set to the table column's datacell...
More involved formatting might require rolling your own subclass of NSFormatter
or setting a delegate to the NSTextCell dataCell of the column of table or
outline view and validating if the key being entered is the one you want.
You might try to search
http://cocoa.mamasam.com (archives cocoa-dev and
macosx-dev lists) for specifics on doing the above suggestions, and if you are
still stuck give a holler.
Have Fun :)
