You just gain the feats, no restriction on how you use them (rangers cant use them in heavy armor, but it doesn’t appear that applies to slayers). You can use two handed weapon feats with a light crossbow if you want (most won’t work because of the nature of the feat, I guess maybe dreadful carnage).

When you are wielding a two-handed weapon or a one-handed weapon with two hands, and using the Power Attack feat, you do not suffer Power Attack’s penalty on melee attack rolls on the first attack you make each turn. You still suffer the penalty on any additional attacks, including attacks of opportunity.
So, you are planning to two-hand the weapon then?
Furious focus only takes the penalty from that first attack though. If you have iterative attacks, it won't help for those. And you'll still be eating that penalty on your opportune parry and riposte.
