We could find the value of $f(g(x))+g(f(x))$ in terms of $x$ and then plug in $1$, but it's simpler to plug in $1$ from the start. $f(1)=\frac{3+5+8}{1-1+4}=\frac{16}{4}=4$, and $g(1)=1-1=0$, so $f(g(1))+g(f(1))=f(0)+g(4)$. Now $g(4)=4-1=3$, and $f(0)=\frac{0+0+8}{0+0+4}=2$, so we have $f(0)+g(4)=2+3=\boxed{5}$.
