Your list is pretty good actually. The only thing I would say is to research certain things more closely. For example - just saying "produce FHGs" is only touching the surface.
If you send out one FHG a week and send it out with just the link to the gallery you can expect to have very few of your galleries appearing on any affiliate-owned TGPs / MGPs.
You need to make it as easy as possible for these guys to use your stuff - and if you own a TGP then the last thing you are going to do is add one gallery at a time - it's a total pain in the ass and very inefficient. So, wait until you have a good 10+ to send out at a time (even more is better) and then send them out in the format:-
# of items|format (i.e. movies or pictures)|niche|Sponsor name (i.e. your website)|URL|Description
Different TGP software needs different fields but this will give the affiliate a good start on adding your galleries.
Moving onto RSS feeds, it is unlikely a blog owner is going to syndicate your feed if you update it erratically. Yes, they could use a hub blog to bunch your RSS feeds in with others and regulate the postings, but it is unlikely they will go to this effort. The best way to get them interested in your RSS feeds is to make sure you update them regularly like clockwork - whether its every week or every month, make sure you stick to your schedule (obviously every week is better).
The only thing I would add to your list is to make sure there are no traffic leaks on any page / site you expect affiliates to send traffic to. (Basically a traffic leak is a link to anywhere that doesn't earn the affiliate money). But other than that, it sounds like you have a pretty good handle on it! Good luck
