This answer is a bit different for everyone. Some people change the keybinds for their attacks to be easier to hit while moving, some people use standard controls with no problem, some use the mouse to move during fights with their other hand on the attacks, some come up with other solutions(gaming mouse?). Its good that youre worried about picking up bad habits early, but this is probly a little premature. At level 10 youve only probly ever fought over-world monsters solo or easy-instance monsters with helper NPCs. Around level 30 youll get a companion, after which point you rarely fight over-world monsters alone. And around level 18 youll get your first mission to venture into a dungeon with a group of other players. When truly solo you might sometimes find yourself moving more often to reduce damage as Yui describes(unless youre out of reach, this doesnt actually make much of a difference). With other players? A good tank will get the enemies mostly looking at him and standing still, freeing you up to focus on putting arrows into their tender places. Generally speaking, youll mostly just need to move when youre standing in a targeted AoE(some archers/bards feel compelled to run around constantly while in groups - this does nothing but occasionally put them out of healing range for no benefit). With your companion? Most DPS players spec their companion as a healer first, in which case you more or less stand where you need to and let them focus on keeping your health up if needed.

Since you specify strafe, i personally have those movements set to "Q" and "E" - both fairly easy to hit without bringing my fingers too far away from the attacks. For most fights im able to position my camera either just before or right at the start and leave it there(which again, for me, is zoomed out almost all the way and looking down at around a 20-30 degree angle so i can see fairly far forward while still having a good angle on any aoes near my feet). If i need to do a big move or a mechanic requires me to switch focus, ill be ready to quickly refocus the camera when im done. And one general tip: if you find yourself unable to move because of your attacks its possible you might be hitting the buttons more often then you need to. Heavy shot can only happen once every 2.5 seconds, hitting it 5 times a second isnt speeding it up or giving you any extra benefit. You do want to press it - if you dont activate it then it wont happen and attacking as often as possible is DPS rule #1, but youll spend a lot of fights not hitting more then 1 or 2 buttons every GCD(global cool-down - those 2.5 seconds between main attacks) which makes it easier to work in some movement. This is especially true once you have some more practice with the system and if you know what to expect from the enemy youre fighting.

And as for the map, itll be second nature to you before long. Starting out they throw a ton of stuff at you all at once, but it doesnt take too long for it all to feel natural. After awhile youll have little problem finding things, and the most important places youll go to repeatedly and theyll become ingrained knowledge. And dont worry about asking "super nooby" questions.
