Panels are generic IMO. With 12v system and PWM controller such as the 30 amp Bogart you are buying Isc (short circuit amps) so that is the rating to look at. The 100s are 6.32 and the 120s are 7.5 amps. So up to four of either panel will work great with the Bogart.
I especially like the Bogart as it ties into the monitor to float the batteries as soon as you get fully charged. Some days you will need 15 minutes of absorption (storage) and other days you may need 4+ hours of absorption voltage (heavy use). I don't have this controller but BFL13 can tell you all about manually adjusting the panels and controller(non-Bogart) every day depending on usage and conditions.
Wire should not be made into a huge issue with PWM. As long as you get 15 volts to the controller you are fine. I would use the MC4 parallel connectors to connect panels in parallel. Then run #8 MC4 cable down to the controller. All Plug and play.
