For sites, you should go with:
1 -
Rohirrim Road instead of
Sleeping Quarters (One takes away 2 twilight from the Shadow player, the other might take anywhere from 0 to 4-6, I'd play Road).
2 -
Rohirrim Camp3 -
Hall of the Kings or
Tower of Ecthelion instead of
Beacon of Minas Tirith (Too early in the game, the healing might not be THAT necessary unless your deck exerts like crazy or something went VERY wrong. If you deck can move consistently, Tower is awesome, a run from 3-6 is always welcome. If not, drawing cards is almost always essentially better than any other thing you could be doing, INCLUDING healing, specially early in the game - and it also helps your shadow side)
4 -
Osgiliath Fallen or
Pelennor Plain instead of
Anduin Banks (Uruks tend to be naturally strong, so strength pumps are not that great. They also tend to do a lot of damage, and these sites are the ones that punish the free peoples the most with uruks. If burdens run abundant, I'd go with
Pelennor Plain, since it adds more twilight and translates in 3 extra damage; otherwise,
Osgiliath Fallen is still
goo enough, translating in 1 extra damage [your choice, which might be better than 3 in the dark] for the cost of 1 less twilight).
5 -
Crashed Gate or
Steward's Tomb, instead of Pelennor Flats (Burdens won't do you squat, while extra twilight and the ability to deny them their heals might, and getting a free site certainly will).
6 -
Minas Tirith First Circle (If you can play
Tower of Ecthelion, since they might end up NEEDING to go 5-7 to keep up, and your site will punish them SEVERELY for doing so, provided you can manipulate the site path to play YOUR site 6 - not to mention, it takes away a much-needed heal against your shadow that they might be needing); otherwise, your choice is fine.
7 - Fine choice (but consider playing the one that lets minions exert for twilight, and also the one that lets you draw cards, if this oen is not pulling its weight).
8 - Site 8 is a matter or setup VS. necessity. If you have a favorable game against a particular Shadow culture, you play the site that helps that culture. Or, you play the site that least punishes YOUR fellowship side (assuming they are playing the shadow culture that is site-friendly anyway) while adding the most twilight.
9 - Your choice is fine.
For sites 8-9, theres a catch, though. If burdening them to death is a possibility in your meta, due to Uruks doing serious damage, you might consider tossing Gollum in the deck, so you can play
Northern Ithilien as your site 8 (or if they use threats a lot to their benefit, it's also a fine choice) and switch your site nine to one of those that deal with burdens. However, I'd advise against it, and if they DO need threats, it's not wise to spend them at site 8 when at 9 they provide a bigger benefit.
