Flash and HTML on WordPress

Hello. I’m VERY new to WordPress and I’ve got a page with plugins running. But now I want to add a plugin like the ones below and I’m lost.
– http://activeden.net/item/music-player-widget/full_screen_preview/336829;
– http://activeden.net/item/neuvo-mp3-player/full_screen_preview/407698.

Could someone give me or show me a step be step guide the make them work on my page?
