>>>is it possible to remove the ram inside of the laptop and replace ti with faster 1333mhz ddr3 ram at the same voltage?<<<
Only if the existing RAM is DDR3.
You must use the same type (e.g. DDR2 or DDR3). The rated speed of the SODIMMs only represents the fastest speed they'll run at.
The actual speed is determined by the mobo/chipset. If you replace DDR2/533 with DDR2/800 it won't go any faster.

Funny that you're looking to save money in one of the few areas where it would be to easy to upgrade.
One way to clearly add a performance increase would be to replace the fragile, slow, mechanical HDDs with an ultra-fast SSD, or better yet a pair of them in RAID-0.
2.5" SATA and PATA HDDs don't come anywhere close to the 250MB/sec reads and 170MB/sec writes of a fast SSD like the Intel X25-E. HDD seek times are measured in milliseconds. SSD seek times are measured in microseconds.
Not only would you be getting a performance increase but greatly improving data security. A dozen SSDs in RAID-0 represent less data risk than a single HDD, even sitting still. If you compare tolerance to operating shock, the increased security of SSDs is even more pronounced.
Add the fact that the SSD draws much less power, 0.15W active and 0.06W idle for the X25-M compared to 5W spinup, 1.8W active and 0.8W idle for the 7200RPM 2.5" Hitachi HDD and it's perfect for a laptop.
The only reason to use a HDD instead of an SSD is money.

And SSDs are very RAID-able:
