Given three coplanar vectors $\overrightarrow{a}$, $\overrightarrow{b}$, and $\overrightarrow{c}$, where $\overrightarrow{a}=(\sqrt{2}, 2)$, $|\overrightarrow{b}|=2\sqrt{3}$, $|\overrightarrow{c}|=2\sqrt{6}$, and $\overrightarrow{a}$ is parallel to $\overrightarrow{c}$.
1. Find $|\overrightarrow{c}-\overrightarrow{a}|$;
2. If $\overrightarrow{a}-\overrightarrow{b}$ is perpendicular to $3\overrightarrow{a}+2\overrightarrow{b}$, find the value of $\overrightarrow{a}\cdot(\overrightarrow{a}+\overrightarrow{b}+\overrightarrow{c})$.
