Does this firmware function with the PCB in this drop? Does it improve the functionality of the PCB in this drop? Can it be used to remap the keys of the PCB in this drop?

ZigguratThe answer to the first question is no, the firmware I linked works only with the PCB I designed. It is based on tmk firmware, which is open source and highly customizable.
The PCB provided on this buy (or at least the one on the previous buy) is based on Microchip's PIC architecture. I have used the ATmega32U2 microcontroller, which uses Atmel's AVR architecture. They are not compatible with each other.
BTW, I was wondering does the PCB you designed come with all the components on it?

TraverseNo, just the bare PCB if you buy from the link I provided and you would buy 10 of them. I pretend to sell the boards that I'm not going to use with components soldered, but Brazilian post *still* didn't delivered them. No tracking number package = lowest delivery priority possible here. :(
How hard is it to put the SMD components on there, any idea? I wouldn't mind ordering 10 of them and soldering some if people are interested and it isn't too difficult.

TraverseI have used 0805 sized resistors and capacitors, and used a through hole crystal, as I have some of them available at my drawer. Using a fine tip on your soldering iron it shouldn't be difficult at all to solder them. You just need tweezers to hold the components. I also used a through hole mini USB receptacle. They are $1 more expensive than the SMD versions but are way easier to solder.
I looked at the PCB in your link earlier and don't see thru holes for LEDs. Will this numpad not support LEDs to solder in ourselves?

RubenMcNoobinThis version do not have LED support. I already designed a version with LEDs, but I need to receive the prototype PCBs of the first version to see if it works or not. :-/
I'm new to this type of shit so could someone give me (and anyone else who is clueless) instructions on how to use this with this switch tester and list what other components I'll need other than the switch tester and this PCB. Just a simple imgur step-by-step would be fantastic. Thankyou.
I realize you've likely moved on from this, but I just got my PCBs in the mail today and I wanted to post the list of components that appear to be necessary to build this board:
1x ATmega32U2 TQFP32
16x 1N4148 SMT Diodes
4x 0805 SMD resistors
-R1&2 - 22 Ohms
-R3 - 10k Ohms
-R4 - Not connected (I think), see note
1x 16Mhz through-hole crystal
1x button switch
4x Capacitors SMD:
-C1 - 10uF
-C2 - 1uF
-C3&4 - 20uF
2x 20pf 0805 SMD capacitors
1x Mini USB 5 pin female Jack Plug
Note:
R4 is connects to pin PD7 on the ATmega
Functions of this pin from the datasheet:
-HWB/TO/INT7/CTS, Bit 7
HWB, Hardware Boot : The PD7 pin can serve as
TO, Timer/Counter0 counter source.
INT7, External Interrupt source 7: The PD7 pin can serve as an external interrupt source to the MCU.
CTS, USART1 Transmitter Flow Control. This pin can control the transmitter infunction of its state.
