You should wait until you receive your corrected W-2. If you file now with an incorrect W-2 and attach the W-7s and then amend your federal return, the amended return without the W-7s will be considered the final return.
You can get an extension to file your return until October 15, 2018, if needed. If you think you owe any money on your returns, you should pay it by April 17, 2018, to avoid interest and penalties.
