i) Whenever there is availability. You must be ticketed first, though.
ii) "R" class. Do a google search for KVS Availability Tool, which is a pay service that allows you to view R inventory on CO. Alternatively, CO.com lets you search for upgradeable itineraries (via a check-box), so you can use that too, but I don't think its as flexible.
iii)Generally, I think so, but I'm not sure how the stopover in SEA might impact this. You might need to call CO, though you'll probably get 4 different answers if you speak to 3 different people.
iv)15K miles. 5K miles only on Y fares.
