Best catalog plugin and article chapters

Hello, could you please give me and advice with selecting right plugin for a product catalog? It will be cool if there will be a function for compare specs. For example, I need a tablet with 10″ display, OS Android… and “click” – show me results 🙂

And my second question – is there any well-working plugin for making chapters in article? For example, first chapter has an url mywebsite.com/htc-desire-review and there will be another chapters with more text to come (mywebsite.com/htc-desire-review/2 for chapter 2, mywebsite.com/htc-desire-review/3… etc).

Thank you for any tips. Regards 🙂
