Hi,
The best advice at this point is to get on and do it, when you have problems come back, but try and see how far you can get first.
The first thing you will need to do is generate the 38Khz signal, you can do this on Arduino, there are lots of code examples for using the timers to do this.
EDIT: As Chargin has mentioned already, there are some restrictions on the type of signal the IR Detector will accept. You can see these on page 5 of the datasheet you linked. I suggest that you do the maths on some of these restrictions and determine whether you think this device is suitable for your application.
