Yes: get a superfast 802.11n Apple Time Capsule (1TB or 2TB)
and store all your music, images, and videos on it. As well as your Time Machine incremental backups. Time Capsule behaves as a wireless external HD to your MacBook: its volume icon sits on your MacBook's desktop. So you don't need that old XP/PC at all.
However, that old XP/PC can also
use that same Time Capsule as a wireless external HD. Although I see no obvious benefit of that since you seem to primarily use your MacBook.
A Mac, connected by USB cable to another Mac, and started up in "Target mode" (hold Command-T), behaves as an external HD to that other Mac (i.o.w. the first Mac's HD is visible on the second Mac's desktop as an external volume/HD). I don't know if an XP/PC can be started up in "Target mode". But even if it can be, it wouldn't be wireless, of course. So it would have to be positioned near the MacBook, and would have to be switched on 24/7.
