You certainly have an ambitious plan worked out for your life. 
Regarding prayers to saints:
All Christians agree that only Jesus mediates between God the Father and humanity.
Nearly all Christians believe in the idea of intercessory prayer, i.e., I can pray to God for you or intercede with God for you.
All those who believe in intercessory prayer would agree that it is a good idea to ask some devout person to pray for one. Catholics take that one step further and say that it is good to ask people who have already made it into heaven to pray for us as well.
The Protestant objections to this are many, of course, but they are not all the same. One group denies that a dead person can hear/see/know anything until the Final Judgment. One group simply claims that there is no mechanism for the prayers of a person on earth to be “heard” by a saint in heaven. Quite a few dwell on the point that one definition of prayer is worship (reserved for God), ignoring that another longstanding meaning of the word is petition or ask, regardless of the aspect of worship.
Catholics can point to the parable of Lazarus and the rich man for some of their interpretation. (Lazarus in the parable is not the man Jesus raised from the dead.) In the parable, after those two have died, Jesus describes the rich man and Abraham in conversation and part of the conversation turns on sending Lazarus back to earth to warn the rich man’s brothers of their potential fate. From this parable, we take the word of Jesus that the dead are not oblivious to everything until the Final Judgment and that there is the possibility of communication between those in Heaven and those on Earth. Obviously, many Protestant groups object to those conclusions.
So, based on the idea that it is good to have people intercede for us (pray to God on our behalf) and that those who have already died in God’s grace (the saints) can actually understand our petitions (prayers), the RCC believes that we can pray to the saints to intercede for us with God.
Burying statues of St. Joseph to sell a house, praying to Jude or Anthony to cure our cancer or help us find our car keys wander into the realm of superstition and polytheism and are not supported by the RCC. It is a really big group without a very tight control on its members, however, so a lot of silly stuff does go on.
I am not about to debate the points, here. You wanted to know the RCC position, and here it is.
