…that focusrite will be fine for now…most common digi mixers won’t give u better results…
for real improvements, u have to spent at least anther one and a half grant again…
so take it slow…logic will overwhelm u a little at first, but it can get u anywhere without any real need for further 3rd party plugins…and reason can still provide some of it’s unique tricks in the background…

if u don’t record that much external stuff, u might wanna consider using overbridge to get ur elektron devices into logic and skip the whole additional audio interface…
