Hey, ChetSinger. Good morning to you. I just read Ephesians 1 and it's talking about both GOD and Jesus. (note that he referres to them as 2 different people)
Ephesians 1 NIV
"Paul, an apostle of Christ Jesus by the will of God,
To God’s holy people in Ephesus, the faithful in Christ Jesus:
2 Grace and peace to you
from God our Father and
the Lord Jesus Christ.
Praise for Spiritual Blessings in Christ
3
Praise be to the God and Father of our Lord Jesus Christ, who has blessed us in the heavenly realms with every spiritual blessing in Christ. 4 For he chose us in him before the creation of the world to be holy and blameless in his sight. In love 5 he predestined us for adoption to sonship through Jesus Christ, in accordance with his pleasure and will— 6 to the praise of his glorious grace, which he has freely given us in the One he loves. 7 In him we have redemption through his blood, the forgiveness of sins, in accordance with the riches of God’s grace 8 that he lavished on us. With all wisdom and understanding, 9
he made known to us the mystery of his will according to his good pleasure, which he purposed in Christ, 10 to be put into effect when the times reach their fulfillment—to bring unity to all things in heaven and on earth under Christ.
11 In him we were also chosen, having been predestined according to the plan of him who works out everything in conformity with the purpose of his will, 12 in order that we, who were the first to put our hope in Christ, might be for the praise of his glory. 13 And you also were included in Christ when you heard the message of truth, the gospel of your salvation. When you believed, you were marked in him with a seal, the promised Holy Spirit, 14 who is a deposit guaranteeing our inheritance until the redemption of those who are God’s possession—to the praise of his glory.
Thanksgiving and Prayer
15 For this reason, ever since I heard about your faith in the Lord Jesus and your love for all God’s people, 16 I have not stopped giving thanks for you, remembering you in my prayers. 17 I keep asking that
the God of our Lord Jesus Christ, the glorious Father, may give you the Spirit of wisdom and revelation, so that you may know him better. 18 I pray that the eyes of your heart may be enlightened in order that you may know the hope to which he has called you, the riches of his glorious inheritance in his holy people, 19 and his incomparably great power for us who believe. That power is the same as the mighty strength 20 he exerted when he raised Christ from the dead and seated him at his right hand in the heavenly realms, 21 far above all rule and authority, power and dominion, and every name that is invoked, not only in the present age but also in the one to come. 22 And
God placed all things under his feet and appointed him to be head over everything for the church, 23 which is his body, the fullness of him who fills everything in every way."
Paul clearly expressed that praise go to "the GOD and Father" of Jesus in verse 3. Verse 2 he sends greeting from both GOD and Jesus. Verse 17 identifies that the Father is "the GOD of our Lord Jesus". Verse 22 identifies the Father as the One who placed "all things" under Jesus.
The entire chaper 1 is about 2 people. Chapter 5 verses 18b-20 are, I've noticed, somtimes translated as 1 full sentence. So, in effect you have taken a portion of a full thought or sentence, depending on your translation, out of proper context.
Ephesians 5:18b-20 NIV
"Instead, be filled with the Spirit, 19 speaking to one another with psalms, hymns, and songs from the Spirit. Sing and make music from your heart to the Lord, 20
always giving thanks to God the Father for everything, in the name of our Lord Jesus Christ.
"Instead, be filled with the Holy Spirit, 19 singing psalms and hymns and spiritual songs among yourselves, and making music to the Lord in your hearts. 20 And
give thanks for everything to God the Father in the name of our Lord Jesus Christ."-NLT
Either way the entire point of his thought was to give all praise and thanks to the Father who is "the GOD and Father of our Lord Jesus" in everything.
As to the grammatical points you raised regarding the comparison from the NWT to the greek manuscripts this is the entire article from the WOL.JW.org official site that answers your question.

P.S.
The last thought in verse 9 highlighted in red is that Paul knew "GOD's mystery" so he should know what he was talking about.
