Like SmAsH commented, this project would be quite difficult. But, if your really interested, here is a list of recommendations.
For starters, you will need a radio with many channels to cover all the functionality you would like to include with your robot.
- 2 (minimum) channels for the two main motors or servos used for driving around
- 5 channels for the robotic arm (assuming a 4 DOF (degree(s) of freedom), with 1 channel used for the servo controlling claw movement)
- 1 channel for the LED
- another X many channels for controlling lasers, airsoft gun, and wall climbing...
basically, your looking at a radio with a minimum of 8 channels.
Next comes the problem of how you are going to 'drive' your robot around. First of all, if you even want a chance at traveling at 13mph, your going to need to use a couple of DC motors, a gearbox, and an a couple ESC's (electronic speed controller, for use with your radio). That setup may get a little pricey, so you can always fall back on using a couple modified servos. A modded servo is basically like the DC motor, gearbox and ESC setup, except in a small neat package. The only drawback is that servos are relatively slow.
So you have a radio and a drive setup complete, now on to the 'extras' you want to add to your project. Lets begin with the 'folding claw' you wish to include. First of all, a claw capable of lifting 4kg's would require some Beefy servos, and a beefy battery: which will end up costing a fortune. Building your own may be a little over your head, so here are some links to places where you can purchase some...(or collect design ideas).

Now for the camera. Shop around or just e-bay for one. here one link:

This will be by far the most difficult challenge of all (no offense, but i doubt you will get anywhere close to wall climbing...) but again, here are some resources:
1. you can use a (brilliant) vacuum suction idea:
