Sorry if I'm late just wanted to clear things up or try to.
Praise & Worship are very close, but the name hints a lot. See how praise comes before worship; praise is basically giving thanks and admiring what God DID, but if Praise & Worship is lead correctly, you should later come out a realm of praise an begin to worship him. Worship is giving reverence and adoration for not what he has done but simply because he is GOD all by himself, you need a reason to praise, you don't need a reason to worship he has already earned it just for being God. The bible says hallelujah is the highest praise, that's basically the capacity of praise, but your praise should be turned in to worship, the praise team isn't there just for the sake of singing, it's to elevate the service in to a mode of worship because God enjoys praise, but he LOVES worship.
