People buy spare lamps since it covers them from being stuck if/when their original lamp goes out. Unfortunately they don't all make it to their rated life and sometimes die without advance warning. Imagine it goes out on the morning of the Super Bowl and all your friends are coming over...

If I were to buy a spare lamp for a PJ, I'd do it something like this:
- run PJ on original lamp through its warranty period (typically 90 days)
- order spare so it arrives somewhere near the end of the original's warranty
- take original lamp out, put it on a shelf somewhere in the spare's box (now you've got a known-good 'spare' in your original - typically lamps don't go bad sitting on a shelf)
- run spare lamp until it dies/dims too much - if it were DOA or died during its warranty period you'd be covered
This way you'd take advantage of warranties on both original and spare, as well as (assuming no problems) having the piece-of-mind of having a working spare on hand.
Availability of bulbs seems to go beyond 2 years - I can still find bulbs easily for my almost-5-year-old HS20.
I should note that I personally don't have a spare on hand at the moment - despite my PJ's second bulb being at its rated lifetime - since I'm potentially going to upgrade Real Soon Now(tm).
I can't offer any advice with respect to your question #2, sorry. Is the PJ still under warranty?
