Studying or modelling (in NLP), people and strategies is something I like and am aware is important to succeed in just about any business, especially IM.
I found this thread really useful as I too am a newbie to this particular forum and can already see/feel the different vibe. I am aware that there are JV's out there who are as different from each other as chalk and cheese. Some are totally supportive and friendly no matter what their success, some are just greedy people who put on a good show and some are only polite and helpful on their way up.
Getting JV's is going to depend on the type of JV's you are attracting. Some more business oriented partners, will look at your product niche and if its a good fit for their list, they will help you and promote. So the need to develop relationships beforehand can be as much about letting people get to know who they are promoting as just getting to know your name.
As I build my list, I will definitely take care about who I promote and who I keep an eye on. I check out the thread on the WSO sometimes and wait for the feedback before I buy myself if I don't already know the developer and the kind of person they are.
I wish you luck with your product launch and think the idea mentioned above about investing your own capital to test the product conversions is a great idea for the type of product you are selling
