I am having problems with ship movement and attack ranges.  For example, my LRM charge right in and get too close to other ships when attacking.  In addition, my other ships of all kind seem to be always be trying to move back together and not attacking enemey ships. 

So, I want to have my LRM ships attack from a distance and not charge in.  How do I do that? 
Second, how to I order ships to attack instead of always trying to reform and then attack?  Because by the time they reform the enemey fleet has jumped away?
Third, is is better to organized ships into fleet or just select them as a mass of ships? 
Finally, it is better to use autotargeting or manually target?
