4) Will I need a visa to travel to the EU after Brexit?

You shouldn’t need a visa to travel to the EU after Brexit. The European Commission announced in November 2018 that, even in a no-deal scenario, UK travellers can still visit the EU without a visa, providing the same is offered to European citizens visiting the UK.  The European Commission has said that from 2021, UK citizens will need to pay a fee (of around 7 Euros) for this visa exemption. This is part of a new electronic travel authorisation system applying to all third country visitors to the EU, similar to the US ESTA regime.
