I am not sure what the question is.

ln does make links. chmod does change permissions. if you read each of their manual pages, you should be in the clear.

with chmod you can calculate the octal number representation, or go the easy way. If I'm just changing 1 permission set I use the easy way. It starts with any of "ugoa", for user, group, other, and all, respectively.

Here is example, output from my terminal:

Code:
[mute@geek ~/lilbo4231]$ touch file.txt
[mute@geek ~/lilbo4231]$ ln file.txt new.txt
[mute@geek ~/lilbo4231]$ ls -l
total 0
-rw-r--r-- 2 mute mute 0 Sep 19 02:37 file.txt
-rw-r--r-- 2 mute mute 0 Sep 19 02:37 new.txt
[mute@geek ~/lilbo4231]$ chmod u+rwx,go-rwx new.txt
[mute@geek ~/lilbo4231]$ ls -l
total 0
-rwx------ 2 mute mute 0 Sep 19 02:37 file.txt
-rwx------ 2 mute mute 0 Sep 19 02:37 new.txt
[mute@geek ~/lilbo4231]$
