I personally own this guidebook and find it very helpful. Its called aiding talmud study. Take a look (you may be able to find it cheaper on Amazon or something but see it first on Feldheims website)

Dont give up. Not everybody learned how to learn in Yeshivah. What it takes is a commitment and dedication to learn how to learn. Just like you have excelled in other areas of your life you can learn to excel in learning. Why is it that when it comes to learning people give up quickly yet they never give up on trying new things in business, trying to make it “big” people have all the energy and motivation in the world and try and try and try.
I guarantee you that in a year or less of serious commitment (a 2-3 hours a day minimum no distractions) you can know how to read the average Gemara without looking at the other side.
