First of all: This is not a full answer.
You should have a directory /usr/source/linux which is really a link to the most recently installed source. In File Manager, examine its properties. It should point to linux-188.8.131.52-10mdk. You work in the linux directory not the linux-184.108.40.206-10mdk one. If this is not so, do not proceed!
Next, go to http://linuxreviews.org/howtos/Kerne...GURATION-INTRO
where the whole process is very well explained.
I would suggest you use the make xconfig option - it is the most convenient one to use.
Remember that, after you compile you need to add the new kernel to your boot loader menu and you will still have the old one available so that if something goes wrong you will still be able to boot the old kernel.
I've done this only once before and am preparing to do it again soon so I'm not in a position to give you detailed help, only pointers and encouragement!
