Acharya I did two independent searches. One from US to london. This flight arrives following morning to the london. Again you can search from London to Ktm. You will find that there is one flight around 11:30 to Abu Dhabi and other two flight in the evening ( or night ishould say) to Doha and Baharain. I don't know how to make these two segment as a single piece which makes life much easier if you have luggage. Orbitz never showed me that route for single US to KTM search. I am trying to use some travel agency for that purpose or ask Orbitz by phone. i have not purchased my tickets yet. I don't know exact answer of your first question as i have not used it so far. But I am guessing that e- ticket can be printed in your printer. The paper has to be mailed by agent by printing themselves so they charge extrar shiping and handling charge. Hope this helps you.
