help? Please

I have a PS2 SCPH-10000 JAPANESE NTSC machine and would like to know how or which chip I could buy in order for I to play USA/NTSC games and UK/PAL games? Any ideas?
Do I have to backup the game and add a patch?
Also I would like to play UK/ PAL dvds and was told I was unable to do this due to the machine being NTSC and unable to play dvd movies in the uk? They also told I am unable to play original USA or UK pal games? Is this true?
Thank you in advance.
