Hey bob le mac,
I should be able to help with both questions.
Part 1:
Sounds like you want to use "closed clamshell" or "closed display" mode, which is what we call the use of an external display or projector while the internal display is closed. You can read about how to do that here:
Requirements for closed display mode:
- Power adapter
- External keyboard, mouse, or trackpad
- External display
Use these steps to enable closed clamshell (display closed) mode:
If you are using a wired keyboard and mouse:
- Make sure the computer is plugged in to an outlet using the AC power adapter.
- Connect a USB keyboard and mouse to your computer.
- With the computer turned on connect the Mac notebook (using the appropriate Apple adapter if necessary) to the appropriate port on the external display or projector and turn the display or projector on.
- After your computer's Desktop appears on the external display, close the computer's lid.
- When you close the lid:
- In OS X Lion and later, the external display will change to a blue screen, then will show your desktop.
- In Mac OS X v10.6.8 and earlier, wake the computer up by clicking the mouse button or by pressing a key on your external keyboard.
You should now be able to use your Mac notebook as you normally would, with a USB keyboard and mouse.
If you are using a Bluetooth keyboard and mouse on a Bluetooth enabled Mac notebook:
- Make sure the computer is plugged in to an outlet using the AC power adapter.
- Verify that Bluetooth is turned on by using the Bluetooth pane of System Preferences or the Bluetooth menu icon.
- Pair your Bluetooth keyboard or mouse with the computer. For step-by-step instructions, see this article forkeyboard pairing or see this article for mouse pairing.
- In System Preferences, be sure that the Allow Bluetooth devices to wake this computer option is selected.
- With the computer turned on connect the Mac notebook (using the appropriate Apple adapter if necessary) to the appropriate port on the external display or projector and turn the display or projector on.
- After your computer's Desktop appears on the external display, close the computer's lid.
- When you close the lid:
- In OS X Lion and later, the external display will change to a blue screen, then will show your desktop.
- In Mac OS X v10.6.8 and earlier, wake the computer up by clicking the mouse button or by pressing a key on your external keyboard.

Part 2:
Sounds like you might need a MagSafe to MagSafe 2 Converter, which allows you to use the MagSafe connector on your LED Cinema Display, Thunderbolt Display, or MagSafe Power Adapter to charge your MagSafe 2-equipped Mac computer.
