Really? Subhan'Allah... getting there is (relatively) easy... staying there is hard!
And I don't think you would have heard what Sheikh Yasir Qadhi was covering before, it's relatively new... in the sense of it being more on the explicit side of things, so as yet other sheikhs are reluctant to talk about it.
The free ebooks
are still available I think, if you download those and read through them, you'll get an idea of what kind of material he's covering, insha'Allah
And alhumdulillah, that's a good attitude to have... may you be rewarded for it, insha'Allah
As for the videos for Like A Garment, they were only small snippets (1 min each, to emphasis a point). The main one is the hadith of Jabir. With regards to the other stuff, unfortunately it's been forbidden to distribute the other (paid for) material... but I don't believe there's an issue with teaching it (that's what we're supposed to do with knowledge... spread it!)
I also have the audio for the weekend course for Sheikh Alaa's "Home Sweet Home" (as well as the course folder), and Sheikh Yasir Birjas' "Fiqh of Love", as well as Mark Gungor's series on marriage (somewhere... I seem to have lost that one now that I've tried to look for it)... but again for various reasons I'm not permitted to distribute them
I think the best thing I can offer you (on the subject of marriage and relationships) are these videos from Sheikh Alaa... I've not watched these ones myself (because I've been to his courses, and alhumdulillah I can and do speak to him directly about any other issues), but it's essentially the same stuff he teaches in a condensed formSolving the Marriage DilemmaDealing with Disagreements
Hope that helps
