EasySocial + EasyDiscuss Login, Register, User Integration

First, I'm not a Joomla user though I have installed it once but never use it. It's workflow confuses me until now .

I would like to buy EasySocial and Easy Discuss but I have the following questions:

1) I'll install Joomla on my root domain (mydomain.ext) but I want that the EasySocial frontpage (http://demo.stackideas.com/) will appear there, is it possible?

2) In the homepage, I would like to include activity stream from Easy Discuss, such as "username posted a new topic", "user replied to xxx topic", etc., possible?

3) In the homepage, I would like to have a block of "Latest Forum Topics", "Most Replied Forum Topics", "Unanswered Forum Topics", "Most Voted Topcis", "Top Posters", etc. Let's say I want to have 10 for each, is it possible?

4) Can the URL /easydiscuss be easily change to /custom_forum_url

5) I would like that the /easydiscuss default content is the list of categories (just like the traditional forums), possible?

6) What will happen to the native Joomla registration form if I install EasySocial/EasyDiscuss, will it be replaced by these extension's own registration form?

7) In Joomla, there's already a User Manager but in EasySocial/EasyDiscuss there's also another User Manager. What's the difference on it? What if I edit a user in Joomla's User Manager, will it reflect in EasySocial/EasyDiscuss too? Or vice-versa?

8) In the demo, there are two users list: http://demo.stackideas.com/easysocial/browse-people and http://demo.stackideas.com/easydiscuss/users Is it possible to have only one users list?

9) Why are the two users list have different data? http://demo.stackideas/easysocial/browse-people has only 5 while http://demo.stackideas.com/easydiscuss/users has different users. Are users not tightly integrated between these two extensions?

10) There are also two user profiles/account options for a single user,i.e.:
http://demo.stackideas.com/profile and http://demo.stackideas.com/easydiscuss/easydiscuss-profile/profile/ashley
http://demo.stackideas.com/profile/edit and http://demo.stackideas.com/easydiscuss/easydiscuss-profile/profile/edit
Is it possible to have only one profile page and account settings/options?

11) There seems to be other duplicates such as http://demo.stackideas.com/easysocial/conversation and http://demo.stackideas.com/easydiscuss/conversation, would like to make it as one as well.
