Vincent, I suggest you get over your pride and ask for the guidance you seek IN the Confessional. If you are unsure of how to go about Confessing, you can and should be able to receive the guidance you seek right there from the start. Just tell Father you’re rusty and how long it has been and he will talk you through it.
There really are wonderful books on the Sacrament. Frequent Confession by Benedict Baur is one. Or perhaps a small guide such as the Confession: Its Fruitful Practice published by TAN.
Good luck and God bless,
