A couple of git questions

[Michael Welsh Duggan]

I've finally started playing with git, and have started figuring out
how I should proceed with my personal modifications, etc.  I have
taken various patches in my personal cvs tree, and merged them into
separate git branches based on master.  I then have created yet
another branch based on master into which I merge (pull) the other
branches (patchsets?), and from which I build.

My questions are twofold...

1) Does this seem a reasonable system to use?

2) How does one use git to create a patch between a branch and master,
   with the intention of submitting it here?
