Do Catholics love their brothers in practice? Well, world-over Catholics are by far the most charitible group of human beings, especially if you consider how many of them give from a position of relative poverty. Regarding loving ones enemies, how many times has the Pope reached out to people of other denominations, religions, and political leanings in friendship and peace? How many times has the Pope called for an end to violence and used his power for the greater good? Go ahead and look it up if you don't believe me, but it's a big number.

1. While some practising Catholics (even members of the clergy) may place the Pope's words or something else above the Bible, this is not officially sanctioned and it goes against what they profess to believe. This is called "Prima Scriptora", (wiki it) and it is the working position of Catholicism. While the Catechism does say "Both Scripture and Tradition must be accepted and honoured with equal sentiments of devotion and reverence.", Tradition with a capital T is later defined as the specifics customs and practises passed down from Jesus through the Apostles. Also, though the Bible is infallible, Tradition is never looked at as infallible, only as worthy of being devoted to and revered.
2. I can't believe you think confessing your sins to a stronger brother or sister in Christ for accountability purposes is wrong, but that's a personal opinion. Attending mass, taking communion, being baptised, etc. are
NOT considered necessary for salvation (if one were hit by a truck after being saved, they'd go to heaven), but those practices are the
outward signs of an inward change. They believe that without the sacraments, a believer cannot fully understand what they have gained in salvation, or what they should do/be as a believer. It is like the seeds which take root but die out for lack of nutrition. If someone accepts Christ and continues on their earthly course without change, what manner of believer are they?
3. You're wrong that Catholicism has secret beliefs. Certain members may have secret beliefs, but the things that Catholicism is defined by are public knowledge. The Catechism (which is friggin' huge) is the definitive statement of faith which any and all real Roman Catholics hold to. The "Compendium of the Catechism" (a new book, actually) is much shorter and I
highly recommend reading it before you go around judging your brothers and sisters so harshly. At the very least it will put your own interpretations of scripture into perspective.
4. Does not all nature testify to the Lord? It is my personal conviction that anyone who is seeking earnestly after God will find Him, and I would rather die then judge another man's salvation. Besides, you're contradicting yourself here, you already said that they require extraBiblical merit to be saved. You're wrong on both counts, but I think it's a mistake made out of genuinely held beliefs and not just bigoted prejudice.
5. The Roman Catholic church has publicly apologised for the practise of indulgences (among other things), though the apology has been criticized as being too sweeping and not specific enough, as most of their apologies tend to be.
I'm not saying that some specific Catholic priests don't lead cults (I have some doubts about particularly extreme sects within the Roman Catholic church), but there are also plenty of people who are attached to mainstream Protestant denominations who have taken their followers in a cultish direction.
I've been to Protestant congregations where the poor were asked to leave or stand outside because their appearance wasn't acceptable, and I have heard a Pastor say that the reason someone's family was suffering was because they hadn't given enough money to the church. I have been told that my own salvation wasn't assured because I wasn't baptised, and that if I really loved Jesus I would do everything within my power to kill Muslim children.
This I believe; there is no innocence where there are men, but there is forgiveness where there is Christ.
EDIT:
The Compendium of the Catechism of the Catholic Church. It's about 150 pages, but almost any questions one might have about the beliefs of the Catholic church are answered therein.
