Hi,
1. and 2. You can do that by adding custom CSS. Here is more documentation about how to do that:

3. I suppose that you have integrated HikaShop with a subscription extension like Emerald or Akeeba Subscriptions.
So I see two possibilities:
- you create two different products, one for the subscription and one for the one time fee and you add them as related products of one another so that a link to the other appear on their product page.
- you create a characteristic with two values for the type of product selection, add that characteristic to one product, add both variants in the variants tab, and edit each variant to configure the different prices and the subscription plan for the variant for the subscription.
