Answer 1

This sounds like a case for configurable products.

For example, you create three simple products "T-Shirt M", "T-Shirt L" and "T-Shirt S" with the respective "size" attribute.

Then you create a configurable product, select "size" as configurable attribute and choose the three simple products from above as associated products. For each simple product you can choose a price difference at this step.

Answer 2

You can do this from custom option also.

Ex. You can add multiple option in product custom option and set price for that. You can set it required / Non Required according to your need.
