To Toothdigger,
I believe God is calling you to the Catholic Church. It is good that you have come to this forum, since you will have the opportunity to ask many of the questions that concern you.
From your post, you say that there are some areas where you agree with CC doctrines and some where you disagree. Rather than examining each CC doctrine separately, the more important issue to examine is whether the Catholic Church is what she claims to be. This is from the Documents of Vatican II, “The Dogmatic Constitution on the Church (Lumen Gentium)”:

“8. Christ, the one Mediator, established and continually sustains here on earth His holy Church, the community of faith, hope and charity, as an entity with visible delineation (9*) through which He communicated truth and grace to all. But, the society structured with hierarchical organs and the Mystical Body of Christ, are not to be considered as two realities, nor are the visible assembly and the spiritual community, nor the earthly Church and the Church enriched with heavenly things; rather they form one complex reality which coalesces from a divine and a human element.(10*) For this reason, by no weak analogy, it is compared to the mystery of the incarnate Word. As the assumed nature inseparably united to Him, serves the divine Word as a living organ of salvation, so, in a similar way, does the visible social structure of the Church serve the Spirit of Christ, who vivifies it, in the building up of the body.(73) (11*)”
Note the Church says Christ “communicated truth and grace to all” through the Church. Also, the Church has “a divine and human element.” These are bold statements, and if they are true, then everything the Church teaches is true. If they are not, then the Church is a liar and is not to be trusted. (Note CS Lewis said the same thing about Christ–He is either a liar, a lunatic, or God–no middle ground here either.)
If you accept that the CC says in Lumen Gentium, then assume that what she teaches is true. Your job then is to discover why she teaches what she does. I have had trouble with many of her teachings, but have always come to agree with her once I know the reasons behind the teachings.
