Re-engineering a YouTube-API based website.

I have a website You can see it working: [login to view URL] Admin: [login to view URL] admin/admin ----- I need to modify this work, it's not yet complete, wanna add: 1I need all features that need authentication: - Info - Favorite - Share - Flag - Like/dislike - Add to - Share - Flag - Subscribe - Description - Statistics I need all available features on YouTube except comments (Everything). 2the upper stream will have all added artists, I wanna create multiple streams and taps at the top to switch between these streams, streams would be: Comdy - Podcast - Gamers ... bla bla bla, just to sort the artists into streams. 3When you first open the website, the right side menu contains all videos, it shouldnt be that way, it should display the latest clips for each artist sorted based on release date, the newest on top. 4I need some optimization, see this artist on my website: [login to view URL] I dont like the naming in the URL, it should be [login to view URL] Also for clips: [login to view URL] It should be: [login to view URL] This would be more SEO friendly. 5\ all right menu bar clips must be sorted based on release date, newest on top. 6Like youtube, the right menu bar should display 20 clips as maximum and a "Load more" button to be there, it must look exactly like youtube related video menu .. as you can see now the one in my website looks a bit bulky wit ha scroller. 7a button called "Comment" should be there, it leads to the clip page on youtube if someone wants to comment or read comments, no authentication needed for that button. All the best
