Adaptor for playstation probably not necessary, just buy a multi-system TV here. Don't bring any 900mhz cordless phones as they are illegal here. The cellular companies operate in the 900mhz band and will track you down and fine you $10K for using a 900Mhz cordless.
Here are the stock answers to the majority of computer/electronics questions originating from North America.
CPU Power Supply: Check the computer's case adjacent to the power cord. There you will find marks listing the model and serial numbers, and acceptable power inputs. If your unit accepts 110-240v, 50-60hz you are in luck. You need to find the small red or black slider switch on the computer's power supply. It may be necessary to remove a portion of the CPU case to get a clear look at the metal box which is the CPU's power supply. You will find the switch to be marked with 110v. Move the slider to the opposite pole, until 240v becomes visible. The computer's CPU is now set to work on 220-240v 50-60hz power input.
Monitor Power Supply: Same drill. Find the marks listing acceptable power inputs. If the monitor lists 110-240v 50-60hz, you probably will not have to do anything further. I believe monitors actually run on 240v, and use a transformer when plugged into 110v. When plugged into 240v, the transformer kicks off-line and the monitor powers up without any further adjustment by you.
Surge Protectors: Leave your 110v surge protectors at home. Even with a converter they will fry. They do not like 50hz power. You can by surge suppressors here for 220v 50hz power input.
Printer power supply: I found it easiest to just buy a 220v power supply for my HP Deskjet. HP has a site here with a very helpful tech support line and parts department. They will deliver the power supply to your doorstep. If you don't have an HP printer, check with your vendor. You will probably find the power supply will not work with 50hz power. I learned that after I burned a hole in the floor after plugging my North American power supply into a converter.
Internet access and faxing...all else is identical to doing it in North America. Cable modem service is available. 56/mo for broadband access, and 46/mo for the cable modem.
Stereos bring 'em and buy a good transformer here.
TV and VCR, leave at home, they won't work here, different tuner.
Look at your electronic device near where the power cord plugs in to the housing. Find the marks in the case or on a metallic plate which list model numbers, serial numbers, and acceptable voltages. Look to see if your unit will accept 50hz power input. (If your unit uses an in-line transformer in the cord, the information will be stamped on the transformer.) If it does not accept 50hz power input, then no, it will not work even with a transformer. The transformer knocks the voltage down to 110volt, but can do nothing about the frequency. The frequency affects the speed at which the electrical device functions. If you use 50hz power on an electric motor, the motor just turns a bit slower, no harm done. If you put 50hz power to an integrated circut, it smokes. You may check with the manufacturer and see if they have a power supply which will work on 220v 50hz power.
