My best piece of advice, - if you don't intuitively get this is to have another player, in a TvT fly against you, and get them to fly in a straight line at varying speeds, and shoot along the path of this straight line from a 90 degree angle at varying distances infront of the target.
Your ping is quite high (on that host, it may be that you or they have bad internet, or there's a big distance between you), so you may want to volunteer for the ping-friendly jobs in coop mode - mainly bombing, strategic targeting (disabling, disarming important things), missile boating or similar.
It is quite possible to be an effective fighter in the 350 ping range against AI, but it does take a lot of practise. - Also, if it's an unstable 350 (bounces between 200-450), it's extremely difficult a skill to acquire.
