normally it is located inside the chassis. some models allow easy access through the bottom access panel. most do not, and require dis-assembly of the entire chassis. if you are not comfortable with it, do not try it, you will most likely FUBAR something during dis or re-assembly... then you are stuck with a dead laptop.
youtube has plenty of tutorials on just about every known laptop from users and IT Pros. again though, if you are NOT comfortable doing this, take it to a repair shop or someone who has IT knowledge and repair skill.
the vent for the fan is normally on the side of the laptop and looks like a car grill. some are behind the chassis between the LCD and chassis. the intake you already know. is the vent on the bottom.
im suspecting you are asking me where the actual HS is because its still overheating.
does your laptop have a graphics device ? or is it a IGP ( Integrated Graphics Package ) based on the CPU? if it is a mobile graphics card, it may have two heat sinks or a fairly large one, which would definitely require base dis-assembly.

Well you can clean the PC of its dust bunnies if that dosent help then consider a new video card something of the 2 - 4GB area for gaming.
depends on the model of the laptop. only the highest end models have the MXM or PCI-E slot that even support the 2GB - 4GB models of VRAM Cards. and those are going to be the 7 series or higher cards for NVidia based. and R2** series for AMD based.
