Here is a link to the Spec Sheet (or "manual") for your reading purposes.

To answer some of your questions, REPORT_SIZE is specified in bits and REPORT_COUNT can be used to specify how many "Usages" are being reported with the indicated properties. For example, you can set the properties for the X and Y usages and the have the REPORT_COUNT specified as 2 (one for X and one for Y) and then specify the INPUT to add those usages to the report. Then continue on describing other usages.

Also, don't forget to have the usages byte aligned. Since REPORT_COUNT is specified in bits, it is easy to forget to have usages byte aligned. So if one usage is only 1 bit, then you need to specify that there will be 7 bits in that byte not being used before moving to the next usage if it requires more than 7 bits.
