Until the update is released, it's not 100% certain, but probably (sadly) no, you cannot.
You will get access to many of the new features, such as Endermen, enchanting, creative mode, etc. But probably not the terrain-related features you mention, such as Strongholds and Abandoned Mineshafts.
The reason is that these features are implemented by changing the terrain-generation algorithm. On the PC version, this means that new terrain features only appear in new chunks, generated after the update is released. But in the XBox version, worlds are generated all at once, on world initialization.
1. Configure server online-mode off
If you are using a proper server you'll need to set "online-mode" to "false" in the server properties. You can ignore this step if you're using in-client LAN.
- Edit
server.properties
found in the parent folder of your minecraft folder.
- Find and update
online-mode=false
The first player should now be able to connect fine as normal with the proper account name, or start the LAN server.
2. Modify displayname of second player
To get the second person connected, first go to your .minecraft
folder. Find launcher_profiles.json
and open it up with a text editor.
Near the end of the file you should find "displayName":
and then your current display name. Edit your name to anything different, keeping the "
s either side of it. Make sure that it's a valid username (only use A-Z, 1-9, and _, not over 16 characters, etc.).
3. Preventing correction of the file
This stage doesn't always seem to be required. If you're having trouble with your name being auto-corrected you may need to either disconnect your Internet, or make the launcher_profiles.json
file read only after having edited your name.
To make the file read only on Windows: right click it, click "Properties", and then tick "Read-only" in the "Attributes" section of the "General" tab.
After you've done that, or if it worked originally, open up your launcher. You should see your edited name in the bottom right:
4. Start minecraft
You can now start minecraft. You can also connect your Internet or make the file writable at this point. Hopefully, you should now be able to join the server with a different name and without kicking off the other player.
Your name may be automatically be corrected if you start the launcher with your Internet connected and the launcher_profiles.json
file not on read-only. You will also be unable to join proper online servers with the fake name, however you can use this method to set it back to your original name, or relog to have the launcher correct it.
Note to others: This doesn't allow piracy in any way. You still need to have a paid account and all of the game files downloaded. It's pretty much the same as /nick
on modded servers.

The two versions are not compatible and can not be played together, especially to a modded version of PC Minecraft.
As mentioned by @MBraedley, the version that was ported is an older version of minecraft (though what I have read says it is based off of 1.6, not 1.8 beta). The matching for minecraft-360 uses Microsofts XBL systems and such, which PCs do not have access to. And a further incompatibility is that minecraft-360 is limited to a world size of 1000x1000.
