Newbie to QR (obviously not to FT) - a bunch of Qs - they might be addressed all over the place, but responses here or links to where I might find things most appreciated.

Award tickets (Business - Q-suites on first segment) issued by AS - OWE + 1 guest. SFO-DOH-Europe. Arrive DOH approx. 1930h, depart approx 1400h next day.
1) Lounge @ SFO? I find references to AS, but wasn't the AF lounge available at one point? (I'm familiar with the actual OW options @ SFO).
2) Lounge options @ DOH?
3) How early to be @ airport for 1400h flight?
3) Lodging options @ DOH? Anything included with the award ticket? Does what appears to be an airside hotel permit exit and re-entry? If landside, what would most convenient Marriott, Hilton or IHG properties?
4) We'd like to take a quick tour - options? Hire a driver for a couple of hours? Easy quick tours to take?
5) Connection is on A320 - how do I determine if the seats are recliners or lie flat?

Thanks!
