USPS First Class International +

[nicknight]

I've got the USPS shipping module set up as follows:

Enable USPS Shipping
True
Enter the USPS Web Tools User ID
395Axxxxxxx
Which server to use
production
Handling Fee
0
Tax Class
--none--
Tax Basis
Shipping
Shipping Zone
--none--
Sort Order
0
All Packages are Machinable
False
USPS Options
Display weight, Display transit time
Domestic Shipping Methods [Everything checked (on)]
EXPRESS, PRIORITY, FIRST CLASS, PARCEL, MEDIA, BPM, LIBRARY

International Shipping Methods [Everything checked (on)]
Global Express, Global Express Non-Doc Rect, Global Express Non-Doc Non-Rect, Express Mail Int, Express Mail Int Flat Rate Env, Priority Mail International, Priority Mail Int Flat Rate Env, Priority Mail Int Flat Rate Box, First-Class Mail Int
Debug Mode
Off

Even though all available shipping methods are activated in the module, I don't get an option for First-Class Mail Int when shipping internationally. In addition to this problem, I don't get any USPS shipping options when shipping to the US, even though all the shipping methods for the Domestic Shipping are activated in the module.
I'm running 1.3.8. Do I need to upgrade the USPS module php?
note: i've got Zone Shipping activated for US currently - would that conflict with USPS? My goal is to have the option to ship first-class, priority & express to the US as well as internationally. Thanks!

UPDATE - I GOT THE INTERNATIONAL WORKING PERFECTLY BY UPDATING THE USPS.php file with the file provided here: http://www.zen-cart.com/forum/showthread.php?t=97461
Thanks DrByte!

NOW: I just need to get it working for the US. Any ideas?

From my experience, people usually find shipping modules failing to quote for certain regions because they've assigned a Shipping Zone restriction in the module's settings, instead of leaving Shipping Zone set to --None--
