How should I wire up the circuit to connect a TSOP4838 (Radio Shack 276-64) infrared receiver to an Arduino

All you need to do is supply a resistor (I used 200 Ohms, with a 3. 3V supply) to the power line, GND it, then connect the data line to one of your digital pins (I used pin #2)`. However, the datasheet shows an example circuit with a 100 Ohm resistor connected to Vs along with a 4. 7 micro Farad capacitor connected between Vs and GND. I`m guessing that I should connect Vs to the 3. 3V output on the Arduino

and use a 200 Ohm resistor, but do I need a capacitor
