if you have applied for AP, then why do you want to get H1 visa stamp??
For H1 visa stamp you need to mail your passports or go to your home country to get the stamp?? either way it is a risk. There is nothing wrong in being cautious before mailing your passports.
If you are applying at the consulate in your home country, there is a small confusion, visa stamp is for non-immigration purpose, but you have filed 485?? contact your attorney, clear all your doubts and then fill in the form.
If you have an answer from your attorney please post here...
