Newbie to Mobile hacking, need pointers to root Galaxy Y GT s6102

Hi All,
Just discovered XdaDev by googling....like the spirit of communal help, hope I can contribute back one day.

Am semi tech on many different things but I've got no 'head space' on mobile tech, rooting and all that goes with it.
The more I read the more I get confused, many posts come assuming you know stuff already or have a 'familiarity',
=MY PROBLEM=
My Galaxy Young GT S6102 keeps filling up as storage is low spec. Due to Samsung forced updates I either factory default it again and run around with no security or Learn to ROOT it and perhaps put a minimal image on it.
=======
Tried looking for my model and although there are some refs here and there I cant find a good NEWBIE GUIDE to do it.
Can someone please point me in the direction with a few links. I'm not being lazy, I spend over 20 hours searching the internet and cant find anything that doesn't leave me with some doubt or missing knowledge [assumed pre knowledge/familiarity].

Don't want to brick my phone, am out of work and can't afford to replace.

cheers all.
