A 4200RPM hard drive is definitely on the slower end of the spectrum, and could easily be responsible for most of the issues you're experiencing. A 5400RPM drive, or even 7200RPM, would be an improvement. But first wipe and reinstall the OS (assuming the OS on it now has been in use for a while, or by the previous owner) to see if that makes a difference. A wipe/reinstall is far preferable to "cleaning up" the drive because it's never possible to know whether you've successfully "cleaned up", whereas with a fresh install of the OS, you know it's clean and that you've reached an adequate baseline to make a determination as to whether or not it helped. I wouldn't suspect RAM, as long as it's PC2700 RAM. And the resets you mention are not going to speed up your computer. You can always downgrade to Tiger 10.4, which will provide a much quicker experience, although you'll sacrifice browser and various software compatibility, and you can't sync an iPhone 4. Keep in mind though that you have a 1GHZ 7+ year old computer with limited processing power, that was manufactured before YouTube was prevalent, so regardless of what you do I would not expect consistent smooth playback of YouTube videos in SD, or especially anything HD. It's important to keep that in mind before investing even $50 in a faster hard drive.
