Goodyear PD is fully encrypted, as is Buckeye PD, the next city to the West. You cannot monitor either of them, unfortunately. To the East, Avondale and Tolleson PD dispatch can be monitored. They are on Simulcast G of the Regional Wireless Cooperative (RWC) trunked system.
For the FD, most of the departments in the Central and West Valley are part of the Phoenix FD Regional Dispatch Center. They have two main sets of channels. The conventional VHF-High "A-deck" is used for fire and HazMat calls.
A-1 154.1900 Regionwide dispatch
A-9 155.6700 Southwest fireground (primary fireground channel for Goodyear and surrounding departments)
The full list can be found here. Scroll down to Phoenix.

For EMS and any other calls, you want to listen to Simulcast G of the Regional Wireless Cooperative (RWC) trunked system. K-1 is dispatch, and carries the same transmissions as A-1. K-9 is the primary assigned talkgroup for the Southwest area departments. K-10 through K-13 are for mountain rescues and major medical calls, such as multiple patient motor vehicle accidents (962 is the radio brevity code for an injury accident).
They also have "L-deck". Officially an interoperability deck, it is used by the PFDRDC for large special events on occasion.
The RWC page is here. Again, you want Simulcast G for the West Valley.

The RWC is a P25 Phase I system currently. There are a few Phase II talkgroups in use at Sky Harbor airport, and it is anticipated that the whole system will go Phase II eventually, although it's not publicly known when that will be. But right now, it's mostly Phase I.
The simulcast sites of the RWC such as Simulcast G which covers the West Valley can be difficult to receive, due to the nature of how they work. Some people have had luck with the Uniden 436HP/536HP/325P2/996P2/HomePatrol scanners, and some of the GRE/Whistler scanners. However, most, like me, have found that only the SDS-100/200 scanners work properly. Others use the Unication G4/5 pagers.
Since every department in the PFDRDC is dispatched on the same channel, you'll have to develop an ear for the apparatus numbers you're most interested in.
Goodyear FD apparatus are numbered in the 181-189 range.
To the east, Avondale is in the 171-179 range, and Tolleson is in the 161-169 range. To the west, Buckeye is in the 701-749 range (they only have 6 stations at this time), and Buckeye Valley is in the 321-329 range.
Welcome to Arizona, and the Valley of the Sun!
