I don't input anything. It's all automatic. I personally would do more than just 12 links because for me it's not just about ranking for random long-tails that get virtually no traffic. It's also about the 301 directing link-juice to a more valuable page without directly loading that page with links. Say I have 1 page for my primary keyword and I build 100 links to it. Then I have 20 pages from this plugin that all 301 to that page. If I point 100 links at each of those pages, I now have 2k additional links directed my primary keyword page but it doesn't look overly hinky because they're not directly linking. Then, I improve it more by building links to each of those 2k links and then more links to those links. By the time it's done, each of the posts created by this plugin will have over 15k links funneling down through multiple tiers and then 301ing to my primary keyword which adds a lot of backlinking power. By backlinking the pages built with this plugin you get the double benefit of ranking for the LT and improving the linking for a real keyword that might require more money and traffic.
I would also do more than just blog comments. Particularly ones from fiverr which are most likely AA lists that have 5000 OBLS and have been hammered to hell. I would *never* link those directly to my money site, even a 301d page. For me, those kinds of links are only for tier 3. Personally, the 100 links I direct towards each post are a mix of platforms including wikis, web 2.0s, articles, bookmarks, social networks, micro blogs and more. Good diversity helps remove a footprint.
But that's just me.
