how to setup this git workflow?

Question

I want to be able to setup the following git workflow but it confusing as to which are the correct commands to use - rebase, remote, etc?

1. Clone an open source project where I only have read only access to their git repo
2. Make changes to the project and save those changes to my private github repo - lets call that 'development'
3. Once dev changes are stable move them over to 'staging'
4. Once 'staging' has been tested then move the changes to 'production'
5. Sync the remote open source project say weekly as its always changing and then start the whole process again.

Thanks

# clone, create and change to branch development
git clone git://the/open/source/project.git
git checkout -b development

# make changes and commit
git add ...
git commit -m '...'

# several commits later, create a branch named staging and change to it
git checkout -b staging

# after testing, create a branch named production and change to it
git checkout -b production

# syncing ( assuming the remote to be named origin and the branch is named master )
git checkout master
git fetch origin master
git merge origin/master

# repeat the process
