Select-Net  (shortcut keys S-N) and then click on the net of interest.  You 
can then see which net is highlighted. Unfortunately it is more difficult 
to get this selection to work across multiple sheets on the project (due to 
the fact that the net is not an attribute of the wire so a global operation 
is not possible restricting wire selection by net).

Once you have the selection you can also get a report of the selected pins 
from the Reports-Selected Pins... Menu option (Sch).  Read the stuff on 
de-selection below to make sure you know what you are getting first.

Mira,  one thing that you should understand (re-you copy and paste 
question) and is relevant here and elsewhere is how Protel selects 
things.  Protel makes a difference between selection and focus.  Selection 
is shown by a change in colour of the entity(ies) usually yellow.  Focus is 
shown by a box around the entity.  At most, only one entity can be focussed 
at a time. Many entities can be selected, independent of the entity that is 
focussed (if any).

Get very used to using the X-A key combination (deselect-all) as Protel 
builds up selections by default, not clearing the old selection. There may 
be an option to change this  I prefer the selection building up.  There is 
reasonable documentation on selection and focus in the Protel docs and it 
is worth reading this.

Selections can be made by dragging the mouse to form a box around the 
desired entities with the left mouse button held down, or by Shift-Left 
click, or by calling up one of the selection processes from the Edit menu, 
or by doubling clicking an entity and changing the selection attribute or 
by ....  (Changing the attribute manually is only mentioned as it is very 
powerful when used in conjunction with the powerful global 
search-and-destroy features of Protel - want to select all 0805 resistors 
with a value of 10k, but just on the current sheet (or the project as you 
wish)? Easy! Just the global operations and do it in one go.)  Learning 
about the various methods of selecting and deselecting areas, inside and 
outside and by layer and type (requires customization) is important to 
running Protel efficiently - spend the time now.

Copy and Cut work a little differently in Protel from some other 
applications, in that they will work on the selection. Also, when copying 
and cutting you need to select a reference point for the paste after you 
select the copy.

Another thing, Protel is extremely customizable.  So it is possible to 
change almost any menu/key combination/toolbar to add in new processes. One 
change I usually do is to add the copy and paste processes to the mouse 
right-click context menu for both Sch and PCB.

One the issue of the net label automagically picking up the GND net from a 
wire with a GND power object attached.  This will not happen in Sch.  What 
you can do is to hover the net label (while it is floating under the mouse) 
over the GND object and press the INS button and this will "clone" the text 
of the power object (in this case the Net). It is under your control rather 
than happening behind your back. (Note that cloning off power objects can 
be tricky at time if the default snap grid of 10 is used.)  Cloning like 
this is a very powerful technique that can be used in all sort of 
situations including when placing power ports, components ...  also worth 
reading about it in the manual.
