Getting started

So I live 30 mins away of two mountains. 45 minutes from the third. An hour to the base of Appalachia and 2 hours from the top. I really want to start hiking and as it's the beginning of the year its a good time to get started (not too hot).

My question is how do I start. (Other than just walking). Is there any gear you'd always suggest or something to help navigate state/national parks. I'm planning on starting to do some easier trails within the month (barring any super cold weather or harsh conditions).
