i guess you covered all bases.
when the churches get more united you'll be sorted as you did all 3 groups!
i don't think you should worry too much, sure maybe you are a bit confused, but this is common, life is complicated sometimes.
i think you should focus on being the best Christian you can be and worry less about what denomination of Christian you are.
when you are closer to God, the rest becomes clear.
so pray and study the Bible a lot, fast (after pentecost!) regularly and also have times when you fast from tv, computer etc. in order to focus a lot on your spiritual life.
go regularly to confession, and ask God daily how you can become more like Him and serve the people around you and accept life's problems with peace and serenity. have a daily prayer habit that includes psalms, set prayers (eg. 'glory to God in the highest' from the catholic mass is fine for any Christian) and spontaneous prayers.
i, personally find the orthodox prayers very valuable and beautiful, but i think any ancient patristic prayers are valuable.
i recommend the orthodox study Bible, i don't think you will find it so 'orthodox' that it's not 'catholic' enough, and there is lots of sensible discussion there on matters of doctrine. also it doesn't get too complicated. once you have read it all, maybe you can move on to more complex theology, but it's enough for me, and i like to discuss doctrine quite a lot.
baptism doesn't 'do' stuff to you that is separate from the rest of your spiritual life. so live as closely to God as you can, follow the example of the desert fathers and the Christian martyrs down the centuries and spend plenty of time in church so you can go out to give God's love to those around you.
then once you've done all this, let us know how you're doing, coz at that time we will need your wisdom and guidance
