As this is already turning into a "Install this distro" thread, I'll try to steer it back on course:

No worries, it's a good question.
If I install Linux OS on separate disk will all the plug-and-pray hardware which previously worked fine with Windoze XP Pro also work with Linux?
This is a wide open question. If I buy a brand new 2005 Honda Civic, can I throw in a 1968 Chevrolet 327? Uh, yeah, you can. But, you may run into problems. Maybe not all your things will work, but some probably will. Try it, play with it, see what works and what needs 'tweaking' or just straight up doesn't work.
The slightly easier answer is to check the LinuxQuestions.org HCL
(Hardware Compatibility List) to see if your hardware is listed, and what state it's in.
Is there a hard disk size limit with Linux? I would like to use a 10GB for OS, a 80GB for documents, and a 400GB for MP3 files. Any thoughts on this?
Yes there is a hard disk limit, but those numbers are nowhere near them. I believe that ext3 is somewhere in the terabytes; xfs is somewhere in the Pentabytes, but I could be mistaken. Either way, it's VERY unlikely you'll reach that, and by the time modern technology in the home comes remotely close, I'm sure the limit will be changed far beyond the current ones.
400GB for MP3's? Seems like quite the addiction to me
Maybe you could use an ID3 tagging tool to ensure you don't have duplicated hogging, oh, maybe 300GB...
