Thanks everybody who contributed to this thread. I missed the launch yesterday, but reading this is almost as good. :)
I always consider space to be the FIRST frontier.

Official Chinese report indicates two maneuvers by TG-1:

新华网北京9月30日电(田兆运、谢波)北京时间9月30日16时09分,在北京航天飞行控制中心精确控制下,天宫一号成功实施第2次轨道控制,近地点高度由200公里抬升至约362公里,顺利进入在轨测试轨道。
这次轨道控制是在天宫一号飞行第13圈实施的。此前,在30日凌晨1时58分,天宫一号飞行至第4圈时,北京飞控中心对其成功实施了第一次轨道控制,使其远地点高度由346公里抬升至355公里。经过两次轨道控制,天宫一号已从入轨时的椭圆轨道进入近圆轨道,为后续进入交会对接轨道奠定了基础。

So:
200x346 km -- initial orbit
200x355 km -- after first burn at 01:58 Beijing time
355x362 km -- after second burn at 16:09 Beijing time

TLEs seems to support the first two, still no for the third one.
This message reflects my personal opinion based on open sources of information.

They raised the apogee first? Interesting...

The first burn was surely simply to check that the propulsion system was working properly and also setting up the required apogee altitude for the second burn to circularise the orbit.

Which pad at JSLC was TianGong 1 (SLS-1 or SLS-2 or another pad)?

The same pad as used for all of the Shenzhou launches: Satori says that this pad is actually designated 921.

The second pad, 603, is only used so far for launches without strap-on boosters and unrelated to the piloted programme.

The one site I thought would be full of information about the successful launch is Chen Lan's "Go taikonauts", but as of moments ago, he still hasn't posted ANYTHING since a day BEFORE launch. What's happened to him?

After nearly a day without updates, Space-Track has started to catch up, with the following orbital data extracted for Tiangong 1 (dates/times are orbit epochs):

Sep 29.72    Incl 42.78 deg       Period 89.82 min     Altitude 198-333 km
Sep 29.86          42.78 deg                89.95 min                 199-345 km
Sep 30.87          42.78 deg                91.44 min                 336-355 km

One half of the fairing fell near Yemugai village (N383631E1094443), Shaanxi province.
About 100,000 people had been evacuated from this zone prior to launch.

I find it astounding that China, a country with a large coastline facing east, still launches far inland, where a large population is evacuated for every launch.

As in "Project 921"?

Correct, except that the pad designator is just "921", I understand.

Fairly typical military/intelligence agency paranoia at work: Put it deep inland far from population centres so that it is harder to insert spies into the site for espionage and/or sabotage.  It demonstrates the site's origins as a top secret military site.

I've read that it was so it was more difficult to bomb. Right in the physical center of their defenses. Of course, launching east from the coast is not very useful for polar orbits. So, given the military needs, well to the north was not a bad choice for initial places.
Once everything was more open they started developing Wenchang. Which, incidentally, will be the only one able to launch the LM-5.
