Newbie problem

Hello, 
I am new to git and gave it a try to version my home dir and
synchronize it between two machines. It works but I think I did some
mistakes in my setup which make its usability non optimal: 
 - push/pull operations need remote address
 - I didn't set up any branch

Here is what I did (lap is for operations on laptop, pc on desktop):
lap> git init
lap> git add ...
lap> git commit ...
lap> scp .git pc:
lap> mv .git git-init
pc> git checkout .
pc> git commit ...
lap> git clone  -n --bare --reference git-init/  ssh://pc/~/.git
lap> git checkout .
lap> git add ...
lap> git commit

Now, I want to be able to do:
lap> git push
or
lap> git pull

instead of 
lap> git push ssh://pc/~/.git

I think I need to reconfigure my remote branches/origin on laptop but
don't want ot break everything.

Help appreciated,
