Homebrew PCBs

hello. 
I have to recive a gerber file soon,and for that purpose, I have 
downloaded "View mate 10" and "gerber magic" .
( I have to make a simple PCB, and the costumer will drill it 
himself ,and he will need the drill holes)

Now , to test it, I made some files from an Eagle project, but after 
choosing to make Gerber 274 X , in Egle ,my files get extensions 
like .BOT  or .cmp .

Now, I can view them in the gerber viewers , but there is a problem. 
I dont get the drill holes .

I can understand, that drill holes will not be needed in the file,as 
the PCB would be drilled with a CNC mashine after etching. 

But is it not possible to get the drill holes in the layout drawing, 
for etching ?
 and second, ARE the files I get from Eagle , Gerber ? They have 
different extensions than gerber. ?
