If Q<K does this imply that delta G is negative, meaning that it will progress in the forward direction or must be still consider temperature, enthalpy, and entropy values as well?

I believe you're right.
If (Q/K) <1 or Q < K, then delta G will be negative and thus spontaneous reaction.
If (Q/K) >1 or Q > K, then delta G will be positive and thus non-spontaneous reaction.
Hope this helps!

It helps to think of this in terms of k in an equilibrium equation to determine whether it will proceed to reactants vs products.

if Q<K and it's spontaneous does that mean the forward reaction is stable?
