Yes, you need to set both. HttpProxy only proxies directory traffic.
HttpsProxy proxies Tor node traffic. Also, if your proxy only allows
connections to limited ports, you must specify FascistFirewall and
FirewallPorts for those ports, or the more recent (and slightly more
complicated) ReachableAddresses config.

Regretably the proxy behavior with Tor is not all that good. For
example, if for some reason the proxy is unreachable, it fails
silently and reverts to non-proxied connections. If the proxy refuses
to allow you to connect to a particular IP/port (for example, if you
do not specify FascistFirewall), it prints out a warn, and then
reconnects without using the proxy.
