Praise and Worship, as I understand it

Praise and Worship is an integral part of any practising christian today and am quite sure that most are aware of the 'what' of it. But just a recap- praise is all about what God has done in our lives and Worship is what is due to Him for who He is. Now, Ive often wondered about the 'how' of the matter. How do I really express my appreciation and my awe to the Almighty?
Is it just by singing all those beautiful songs with weighty lyrics (For the naive, it is fast numbers for praise and slow ones for worship)?
Or is it by bowing/handlifting/prostrating/waving/clapping/jumping etc? Does it end there? One thing that struck me was that as Jesus points out in John that God is Spirit and we ought to worship Him in spirit and in truth, so it doesnt just involve our bodily actions or our vocal cords. It is beyond the flesh. It involves the spirit within us.
I have often experienced an aloofness in my mind and spirit even when my body was performing those actions of devotions. And one thing I understood is that people can be easily fooled by my outward piety and I have seen that we all are good actors. Our heart, our inner self, can be completely detached from what we do and yet we so well deceive everybody around us. How often have we pasted our best smiles for our rivals while our heart was bitter and even scheming the worst for them. Maybe, what I have described so far happens to me alone, and I thank God that you are such a perfect human being!
Alright now for all those imperfect humans like me, let me continue...
So here's my question - even if I put all my heart, spirit, soul, strength in singing a song and really do mean it when I sing unto God, does my job of praising and worshiping Him end there?
My relationship with God has always evolved through my relationship with others. From my marriage I knew about love unconditional, forgiveness, the importance of being faithful, about trust and commitment. When I became a mother I could feel, atleast in lower degrees the kind of love God has for us as a Father. Just so, I understand that to appreciate my husband, I neednt sing songs the whole day to him (it would be so boring, especially when you are not a good singer)but I would show it through words and actions. I might even praise him in front of others to show how much I care about him and about what he did for me. If I really love him, I would never want to hurt him on purpose and my actions would speak better than hollow words. (This applies the other way round too).
So praise and worship doesnt really involve songs alone, it is just the tip of the icecream, cream of the cake, whatever, as long as you catch my point. The real thing is to be obedient to God, to be real followers of Christ and His principles (if we really worship Him). And how do we do it, but to show Christ-likeness in theraltionships He has placed us on earth, This is our real witness, much more deep and powerful than when we stand on a podium, preach and leave the place for good. Let them see the real 'me' and 'you' devoid of our masks. Let them see what we are made of , same as they are but the difference being our obedience to our Lord Jesus, Who prompts us to stand up each time we fall, to forgive, to endure, to show mercy, to encourage, to lend a helping hand and to shower love, expecting nothing back. That is the hardest part (wish we could just sing away to glory) but this, I understand, is true praise and worship.
