Hi Eric....
Thanks for the quick response, at the moment i can't really tell if theres any problem,since I've upgraded to an SSD and 16 GB Ram my machine runs very fast,the reason why I've upgraded was the lack of speed beach balling and very high cpu usage by Kernel task Window Server and a few others,in the end the most reasonable solution for me was that i also had not enough RAM.
Like i said in the first post i started out getting into Terminal executing a few of the simpler sudo cmds and stumbled upon these jobs.
