Here's what Cafe Astrology says about your NN and SN.

"North Node in Scorpio and/or in the Eighth House

With North Node in Scorpio, our South Node is in Taurus. With North Node in the eighth house, our South Node is in the second house.

A tendency to be overly self-reliant and set in our ways, to cling to our possessions (material and otherwise) and habits, to be too fearful of crisis and overly focused on security, and to attempt to achieve success through sheer will rather than listening to our sixth sense are some of the issues this position suggests. With this position, we need to loosen the grasp we have on the things and people around us and open ourselves up to our soul's need for transformation, change, and regeneration. We may experience difficulties in partnerships because we tend to be blind to others' values and worth, expecting them to share the same values as us. We, in fact, not only need a partner, we need to learn the value of true partnership and intimacy (sharing) in order to gain the security we so crave! But, first we need to move away from our instincts to support ourselves, and towards sharing with significant others. We may fear taking chances and we tend to resist change as well as input from others. We may find ourselves imprisoned by the world of the five senses, and need to learn to fearlessly confront the possibility of crisis and change in our lives. Moving out of the seemingly solid and stable material world can seem intimidating. But clinging to things and people that are either outdated, limiting, or counter to our growth will steer us in the wrong direction. Releasing ourselves from our attachment to doing things our own way will help us find inner balance and satisfaction. "

It's interesting your SN is in the 8th house because that's the natural house of Scorpio so it would give it some Scorpionic influence. It's also interesting that your sun sign is Taurus because that's your SN but since it's also in the 8th house it too has come Scorpionic influences. But one thing that will mean to you is that because your sun sign and you SN are both in Taurus you'll have a harder time moving from your past life influences of Taurus to your current life's goal which is Scorpio. You are going to have to fight yourself and your rising sign is not going to help with that one bit.

Your rising sign it the self you show to the world. Libra Rising has a tendancy to have boundary issues and lose itself in relationships. That's the complete opposite of a Scorpio who has a very clear sense of self and a dominating will (which Taurus too has by the way). Libra wouldn't start a fight to save it's life or anyone else's for that matter. They would rather go along with a lie than to stir the pot and risk hurting anyone's feelings. They also see both sides of everything so it's hard for them to draw a line in the same and take a stand. Or they take a stand then end up constantly changing their minds as they see the other side. Scorpio will draw a chasm in the sand if they have to put it there with dynamite and they won't spare anyone in pointing out the truth. They'll shove the truth of any situation down the throats of those around them and tell them to quit their whimpering and grow a spine. Very opposite in the way they deal with things. So your Rising Sign will do it's best to put the clamps on Scorpio behavior. Taurus would give you the stubborness, determination and sheer will to carry out the Scorpio but to Taurus if it is living in a cozy home with a nice job and friends who love to eat and party it will be happy. It also has enough sensuality to take on Scorpio sexuality and just give it a sensual spin (think food, wine, silk, etc. used in sex games and you have Taurus gone Scorpio). These signs both have a tendency to get possessive of partners so they can also play into each other that way. Scorpio is just far more intense and sees much more of the underbelly of the world which would upset a Taurus no end.
