The only true safe way to work with electronics is with the use of an anti-static wrist wrap (that is connected to electrical ground). The reason I am skeptical of the other products is the fact that they provide no path for electrical discharge of any static electrical charge on your body.
The anti-static wrist wrap provides a path to ground for said static electricity, through a current limiting resistor, to ground. Without a path for electricity to flow, there is no way to discharge this static buildup. Just due to that scientific fact, I will argue that products 2 (anti-static release discharger keychain) and 3 (anti-dissipative wrist strap) simply don't work.
As for product 4 (rubber finger covers), this would work, but only to a limited extent. The rubber provides a good insulator between your skin and the conductors, but if there was enough buildup of static electricity in your body, it could theoretically overcome this resistance. That being said, the resistance of rubber is extremely high, and I would recommend this product over 2 and 3.
At the end of the day, your best (safest) bet is to use the anti-static wrist strap ("grounding strap").
Oh, and as for that anti-static screws box, don't bother. If you use an anti-static wrist strap, and you are in direct contact with the screws/screwdriver, you shouldn't have a problem. If you do go with it, I believe you would need a magnetic screwdriver (otherwise how would you get an individual screw out without flipping the whole thing upside-down?).
