You can still air dry with gel, if it sets with a crunchy feel that is normal with many gels, especially if you use a fair bit. It is called the gel 'cast' and you can either leave it to wear off naturally or you can scrunch it out once the hair is dry - known on here as scrunch out the crunch (SOTC!). How your hair feels after gel will be a bit of trial and error, some people love them, some prefer other types of styler. Seems like with your long hair you'll want to find a gel that is quite easy to distribute. You will probably want to use a bit of leave in/coconut oil under the gel.
You may need to low poo sometimes if you use a lot of oil regularly, if and when you do co wash it out you can try putting a bit of cowash through the length, leaving for a minute then massaging over hair/rinsing out.
