What’s the recommended speed for foo

Entirely depends on your opponents. For for me at the moment that means I have 260 on FOO (before the +30 bonus from zKRU lead). In more developed shards 270+ is needed.
If you have speed from mods on your FOO that give you 4 or more extra speed than the opponents mods give their Vader, after zKRU lead bonus and vader's unique bonus, FOO should go first (given standard empire/sith teams). With variance in the opponents team or w/o KRU zeta just add up the bonuses and mods as needed included with FOO 145 base speed and vader 121 base speed. If your FOO is going first you should be winning on offence at least.
Once you have the first turn use marching orders on one of FOST/FOE/kylo to get whole team to go next. At a later point of development of your opponent's you may begin to see one or two exceptions. Just to give an example, if the opponent's nihilus unique has a zeta under zEP lead, you may consider opening with pinning shot instead so as not to cleanse a debuff first turn. But, just mentioning it as the exception.
In summary, find your fastest competitors and mod a bit faster than them... simples ;)
For team comp as already said above aim for using zKRU(L), FOE, FOO, zFOST as a core. The 5th can be filled depending on opponent by kylo/FOSFTP/Thrawn. FOTP can take FOE's place until you have FOE. If you get raid han later he can be used on offence instead of zFOST when opponents team goes first but do not leave this team on defence for longer than the few mins between battles.
For Hpit solo, the fastest auto FO team is zKRU(L), FOE, FOO. Add two others (fost and phasma preferably) to do it at lower gear.
For Haat solo from 20% left in P2 to the end you'll want zKRU(L), FOE, FOO, zFOST/kylo, Thrawn
