Given the sequence $\{a\_n\}$ that satisfies the equation: $a\_1 + 2a\_2 + ... + na\_n = 4 - \frac{n+2}{2^{n-1}}, n \in \mathbb{N}^*$.

1. Find the general formula for the sequence $\{a\_n\}$.
2. If $b\_n = (3n - 2)a\_n$, find the sum of the first $n$ terms of the sequence $\{b\_n\}$, denoted as $S\_n$.
