With Khan split I would attack West if his stack is in the East. You will need more Grenades - can you sell any techs to raise cash for upgrades? His Western cities should fall easily if his forces are split like this.
Unfortunately you have a long border to defend in the East. If you can keep a big stack of cannon in reserve and hit his stack with it rather than letting him hit you then you should be OK.
I would rush printing press only if you think you can get good trades for it - which I doubt. So may as well proceed with Steel, stop research to raise cash for upgrades and then hit Khan with cannon. Lots of cannon. If your economy dies in the process, you can cottage the continent once its yours and catchup.
