Q1) so how do I get the new User to my website after they sign up through WC Subscriptions?
After a new User is created in WC *Subscriptions*, he will get an Email with login details and link, he will be able to click the link and login into your website, this part is managed by "WC Subscriptions" and Woocommerce plugin,.
After the user login into your website, you can show him a wordpress page( Toolset Account page), in this page you can show him a post view:
filter by the post's author is same as current logged in user:

And display Toolset form for creating new post and Toolset form for editing existed post, so user will be able to manage their own posts.
Q2) Is this done on the WC Subscriptions side (e.g. a redirect from WC Subscriptions) If so, to where at TS?, and how to do this?
Yes, it is done on the WC Subscriptions/Woocommerce side, see the screenshot of above document:
hidden link
You need to enable option "Enable customer registration on the "checkout" page", so the visitors will be able to register in your website in the checkout page, after user complete the order, he will get an email with login details
Q3) is this done in Toolset through the User page where it shows the new User? If so, how to do this?
No, see the bottom of above document:
You either use User Forms with regular WooCommerce Products or you add new users via WooCommerce Subscription.
Q4) Or....some by other method??? If so, how to do this?
