There's a new, interesting website that allows you to search public transport routes in Moscow. You enter your starting point (street or address) and your destination and it tells you the best public transport options (buses, trams, metro, etc). Could be very useful when you're trying to get somewhere that has no nearby metro station. Here's the site:

Moscow Public Transport Search

It's still in Beta version and at the moment there are some problems with entering street names (it's not clear what transliteration is needed). But the 'Object' search currently works well. And the Russian language search works fine.

Update: Way to Russia in cooperation with RusAvtobus created our own version in English, where you can mark the locations on Google Maps. Check out Moscow Guide -> Public Transport Search

Just a quick warning for those planning to take Trans-Mongolian or Trans-Manchurian train journeys in late July or August. Due to the Beijing Olympic Games, tickets for trains starting in Beijing will not be able to be booked the usual 45 days in advance. They will go on sale only a few days in advance.

There might also be some trouble obtaining tickets from Mongolia to Beijing at this time. Tickets on this route can still be ordered in advance, but due to high demand there might be problems. Some agencies are recommending clients should fly this part of the trip.

Trains within Russia, from Russia to Mongolia, and from Russia directly to Beijing will be unaffected. At least, these tickets shouldn't be too much harder to obtain than they are any other year.
