If the observer suddenly starts moving towards the light source, he
will observe the source to emit at a *lower* frequency and he will
observe the reception of the crest at a greater frequency. Confusing
huh ?

Is the observer observing the frequency of the source or the frequency
of the received signal?

And realize that there are two factors involved in the Doppler effect:
Time dilation which changes the frequency of the source ( wrt
observer) and the classical effect of the source "catching up" ( or
receeding) to the wavecrest.  The first tends to reduce the received
frequency of the crests and the latter tends to increase the received
frequency of the crests. The net effect is an increased in the freq.
of the received crests ( for an approaching observer/source) and the
value is given by the relativistic formula for "Doppler effect":
f_received = f_proper * s(1+b)/s(1-b).
