Pro Site CSS & Choosing Plan -ish issues.

To make things simple,
I have two irksome issues.

Just for some added information, I'd like to note -
1. I have "Signup on Checkout" disabled.
2. I have free plan enabled.
3. I am using "New Blog Templates" at signup

Time to get to the missions!
Here are the quests -

1. There seems to be CSS conflict which is messing up how the pricing table appears

2. After signing up, when the user tries to access the backend of their newly created site, they are redirected to the pricing page - which is absolutely fine however, clicking on "Choose Plan" doesn't get them anywhere. Even on the free option.

Hope to resolve this as soon as possible. Please do help out.
Thank you.
