I don't see the problem is that there are gaps, it's that it's just too much stuff. The reason it seems spammy to me is that it's a big dump of stuff that isn't well categorized. To really get on top of all that stuff is a huge project, and the best way you're going to do it is by solving problem sets for a few years. From my current viewpoint, I'd pick something really specific (say, modern models of quantum black holes) and try to develop the straightest line to it. Of course, I blew 9 years getting an undergrad and grad degree so I've got that base.
