It all depends on where you live as to whether you are required to abstain from meat on all Fridays. In the United States, you are required to abstain from meat on Ash Wednesday and all the Fridays of Lent. In addition, Ash Wednesday and Good Friday are required days of fasting. This means one normal meal and 2 snacks. Children under 14 and people with medical conditions for whom fasting is not recommended are exempt.

All Fridays are a day of Penance to be observed with either abstention from meat or a choice of various penances. These can be any of the Corporal or Spiritual Works of Mercy. I have not been able to pin down whether this is required or not. Some say it is and others say it isn’t. Even so, it is highly recommended.

The practice of fasting on all Wednesdays has fallen into disuse. This could be a personal devotion if you wish but I would recommend that you discuss it with your priest or spiritual adviser before embarking on this course.
Holy Days of Obligation also vary depending on where you live. In the US, they are:
All Sundays
January 1, the Solemnity of Mary, Mother of God;
August 15, the Solemnity of the Assumption of the Blessed Virgin Mary;
November 1, the Solemnity of All Saints;
December 8, the Solemnity of the Immaculate Conception, patroness of the USA;
December 25, the Solemnity of the Nativity of Our Lord Jesus Christ (Christmas).
Other things you could do is join one of the groups in your parish. There are a number of organisations like St. Vincent de Paul Society, the Newman Society, Legion of Mary, prayer groups, the choir. Find out from your priest what groups meet at your parish or just read the bulletin. They usually have the meeting times. Ask about what they do and choose one that interests you. Just show up and introduce yourself. These are some of the ways we use our talents to help build up the Church and to live Christian lives.

If you look at the top menu across the forums site, you will see links to the home page of Catholic Answers. The Library has some good resources. You could probably find some more answers there.
Beyond what the Church requires, I would advise against trying to add too many things at once. It can get to be too much and can cause you to falter by being too hard. Go easy, work up to it. I know what it is like when you are on fire with a renewed faith. Just don’t burn out too quickly. Nurture your flame. You really should talk about this with your priest or confessor.
