It's the SK100 beltpack transmitter, G3 or G4 will work so long as the frequency ranges match up. It's the same unit as used for lapel mics etc, you just need the correct jack to locking mini jack cable for it. The official Sennheiser ones aren't the best, but Designacable do some really good quality ones with Neutrik jacks for about £25. 

As far as advice on using multiple systems together - it can get complex depending on how many you're using, but there's a few simple things you can do.

It's good practice to always scan for clear frequencies at each venue (under "Easy Setup" > "Scan New List" in the receiver). You can scan on one unit, and program available frequencies in to all units based on the results of that scan - switch all your transmitters off before doing this, otherwise it'll pick those signals up as being in use already and mark them as unavailable. 

Sennheiser have groups of frequency presets, and the frequencies within each group are picked to work well together with minimal intermodulation, so staying in one group is desirable. 

It's also wise to keep some distance between transmitting and receiving antennas - so get your IEM systems antenna away from the one for your guitar/mic receiver at the rack. Likewise with the belt packs - guitar pack on your strap, IEM pack on belt/pocket/whatever on the opposite side of your body.

About to invest - not using wireless atm

Then go for a transmitter receiver on the free channels From 863.100 MHz to 864.900 MHz or digital ones as the frequencies your transmitter is on isn’t legal anymore

What is a UK Wireless Microphone Licence?

There are two types of UK Wireless Microphone Licence.

UHF - UK wide shared access to Channel 38 (606.500-613.500 MHz) internally or externally and licensed on a non-protected basis for either one or two years.

Users can typically achieve 10 radio microphones in this range operating in the same place at the same time. However this can differ case by case. Access is not restricted to specific frequencies and users can re tune within the stated range to any usable frequency.

VHF - UK wide shared access to 15 spot frequencies in the range 175.250 to 209.800 MHz internally or externally and licensed on a non-protected basis for one year only.

These licences are popular due to the one off purchase with no requirement to notify us of where or when these channels are being used. However as the channels are shared users must be prepared to retune to alternative frequencies if interference from other local users is experienced.

afaik - this is current -  all manufacturers still selling ch38 kit

He's using Ch 38/Sennheiser GB band which is absolutely legal with the correct OFCOM PMSE license and is the most commonly used frequency band in the UK for professional systems.
