You don't need SLC. Just your Bachelors Transcript. If you want course by course then it is UDS 160. But you only require Doc by Doc so it is just UDS 105. May be fee have changed better check their website. They have lots of upcoming events in Tri State (NY,NJ,CT) area if you live in Tri-State area you can attend those seminars and ask in person. 

Again if you are sending document from Nepal bettersend them directly rather than relying on University. You can write University name as a sender and via express courier service to expedite the process.
