Since the SF500's have two SFP ports and one combined RJ-45/SFP port, I should be able to link them together using the combined RJ-45/SFP ports. Is this correct? Yes, you use the TwinAx cables 1/3/5m only no 7 or 10m cables example SFP-H10GB-CU3M=
Being the 2960 has 1G SFP ports, I should be able to link it to the SF500 stack - correct? Correct, Yes, you can use either RJ-45 or fiber cables just depends on the length you need to go. Please refer to the datasheets for the switch to see the supported modules. If you want to use the uplink ports on the 2960 and need copper, you have to buy GLC-T= then you can plug RJ-45 cable into it. On the SF500 it has combo ports so you can directly plug in RJ-45 cable. Now you don’t have to use the uplink port for outbound traffic you can use the access RJ-45 ports too. It’s up to you which way you want to.
What model of GBIC should I use for the 2960 as I don't understand the differences? GLC-SX-MM / MMD or GLC-LH-SM / SMD? The ones you listed need fiber cable to go between switches, and the difference is the distance you can go. Please look at Table 1. SFP Port Cabling Specifications - http://www.cisco.com/c/en/us/products/collateral/interfaces-modules/gigabit-ethernet-gbic-sfp-modules/product_data_sheet0900aecd8033f885.html
What model of GBIC should I use for the SF500 to link the two (stack) together and to link to the 2960? MGBSX1, LH1, LX1, BX1...? To stack them please refer to answer on the first question. (TwinAx cable passive only) // To connect the 2960 and SF500 together over fiber depends on distance between, cooper cable is the cheapest.
How about the fiber cables? What is the best/cheapest brand? Only 2ft long or shorter required. I use Belkin fiber cables but there are a lot of vendors out there.

I'm a newbie to Cisco switches (for that matter - any switch) and know enough to make me very dangerous. I was recently hired by a small company to replace their MSP. The company is growing and I want to make sure the core network is able to grow with the company for the foreseeable years and that entails creating a Vlan or two to get everything off the flat network.
Currently we have two SF-500-24P PoE switches stacked, one Catalyst 2960 SI and one ASA 5505. From what I understand and have read, the ASA is doing the routing of the network because the 2960 is in the middle and SF500's are going through it to the ASA. The SF500 was added when the company went to VOIP so the MSP just connected them to the 2960. So I have users, printers and random other equipment using both switches, and of course, all users with phones are on the SF500 only.
First, the two SF500's are linked using cat 5e from port G25/S1 of the Master to G25/S1 of the Backup. Can I connect these using Gbits and fiber/copper? What ports would I use to link and what Gbit connectors?
Second, I plan on using the SF500 to route the new Vlans so I want to move it up and connect it to the ASA. With that in mind, How can I connect the 2960, which appears to have GBit ports, to the SF500 using the same? Currently connected using cat 5e.
Any guidance is appreciated as I have no previous 'hands on' experience - just enough knowledge.
