Ready Boost is actually pretty bad. Microsoft has been disabling it by default in the latest patches due to security flaws. Also, RAM is magnitudes faster than flash memory used in USB sticks. While the access times are shorter than regular mechanical hard drives, the sustained transfer rates are no comparison.
DDR2 RAM has transfer rates of 6400 MB/sec or even higher. DDR3 can achieve over 10,000 MB/sec. USB flash, memory sticks, SD cards, etc memory typically gets about 6 MB/sec (more or less depending on quality).
Most solid state NAND flash drives get upwards of 200-300 MB/sec and with the latest SATA III generation about 500-600 MB/sec. As you can see these still don't get anywhere near RAM.
On your second point, I do know what gpedit.msc is, but I don't know exactly what tweak you're speaking of.
