This one is easy. Select your button, then go to Tools > Show 
Inspector in the menu bar. In the Pop-up button at the top of the 
inspector, select "Size". In the auto-resize box, a strait line meens 
that that value will remain static/fixed, so if you want the button 
to stay at the bottom right, just click the top and left bar to make 
them into springs. If your button is inside a view, apply this 
technique to the view instead.

You might try to look at http://www.cocoadevcentral.com/. They have 
some pretty good tutorials.

Basically, you want to have an object in your nib that will serve as 
a 'datasource' for the table view. You sould connect your object to 
the datasource outlet of the NSTableView. Be sure to select the 
NSTableView, and not the NSScrollView. The, in your object, implement 
the following methods:
- (int)numberOfRowsInTableView:(NSTableView *)aTableView
and
- (id)tableView:(NSTableView *)aTableView objectValueForTableColumn:
(NSTableColumn *)aTableColumn row:(int)rowIndex
In the first one, you will tell the table view how many rows are in 
your table view
example:
- (int)numberOfRowsInTableView:(NSTableView *)aTableView
{
   return [myMutableArray count];
}
In the second one, you will tell the table view what will be 
displayed in each table cell. Also, in interface builder, give each 
table column a specific identifier, so you can know which one your 
working with. Also, you mutable array should be filled with 
descriptor objects, that have methods to access each record.
example:
- (id)tableView:(NSTableView *)aTableView objectValueForTableColumn:
(NSTableColumn *)aTableColumn row:(int)rowIndex
{
   if ([[aTableColumn identifier] isEqualToString:@"Name"]) {
       return [[myMutableArray objectAtIndex:rowIndex] name];
   }
   if ([[aTableColumn identifier] isEqualToString:@"Age"]) {
       return [[myMutableArray objectAtIndex:rowIndex] age];
   }
   return;
}
Finally, to refresh your table view, send [tableView reloadData]; to it.
