How do i edit 40k Source?

[Revox 0]

So i have a small problem mostly due to my lack of knowledge about source for Metin2. Im using 40k Source for my server and i would like to edit things like:
- change max level from 105 to 180
- add so that Yang cannot be dropped on the floor
- 100% for stone to be attached
- 100% skill P at 17
- Remove 3% Tax 
- Remove x3 price in different kingdome
However i have no idea where i am supposed to add or edit such thing since this is Source i know that i can't just use Diffs.
I know tha ti have a directory where the source files can be found via FTP:

Would someone be able to explain where to start or what programs i will need or link a detailed tutorial on how to edit metin 40k source ? 
Thanks in advance!
