Hi
Firstly, the site looks great Tweeders, well done!
Re: the limit of products on Clickbank. Just to clarify, you can sell a maximum of 50 products through a Clickbank account, however this only applies if you are actually doing the selling - ie, customers are paying you and downloading from your site.
As far as I can tell, the majority (if not all) of the links to ebooks on your site are affiliate links, which means that you are simply referring customers to someone elses site and then they deal with the payment/delivery aspect of things. If this is the case, then you can sell as many products as you like - there is no restriction on affiliate links - if you want to offer the entire Clickbank catalogue then thats fine
Also, in respect of the 'thank you' pages, again, this is only relevant if you are doing the actual 'selling'. You don't need to worry about this as the websites that you are linking to will have their own thank you pages. (A thank-you page is basically the download page that Clickbank send the customer back to after their payment has been processed).
One thing that I would recommend you consider buying at some point is a product which I think I have mentioned before - Affiliate Link Cloaker, as this allows you to get rid of the Clickbank hoplink type links and use something like the following instead:

It looks a bit more professional and it isn't nearly as obvious that the link is an affiliate link and will help you in the fight against stolen commissions
Hope that clarifies things.
Best regards
