I'm not sure, but you might try swapping the RX and TX pins, and try connecting the CTS or RTS or DTS lines from FTDI to UART. I don't use the UART connector much myself, but what you're trying to accomplish is getting extremely close.

The BT1 and 2 leds will flash alternately when the module is ready to pair. It doesn't care that you're trying to change some settings.

BUT if the BT1 and 2 leds flash 3 times together and then stop, that means the RN52 is in DFU mode, which you don't want (unless the module needs upgraded to FW 1.16, but most RN52 already have that). You'll be able to see what version it's running soon when you are able to successfully send commands to it.

Thanks for being a trooper and sticking with it trying to get it to work! Most people would have given up a long time ago and cursed us for their troubles :)
