If you want to use the COS/COR output from your GM300 the COS/COR on pin 8 is (active low). Many interfaces need a COS/COR input that is (active high) at 2 to 5vdc. You can make up a circuit to convert the output from pin 8 or take a COS/COR output from inside the radio that will give you a (active high) output. You will need to access the logic board on the underside of the radio. Remove the front of radio and the bottom cover and lift off the RF shield. See photo below.

To obtain Motorola software see the Sticky in the Motorola forum.
The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.
For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).
This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.
