He starts off saying "The factors which detract from Zeal are those which promote laziness" later he says that "Another deterrent to Zeal is trepidation and fear in relation to what time may bring," then he says:

which our Sages of blessed memory interpreted (Devarim Rabbah 8:7) as an illustration of the extent to which vain fear can go to separate a man from a good deed: "Solomon said seven things in relation to the lazy man: If people say to the lazy man, `Your teacher is in the city; go and learn Torah from him,' he answers, `I am afraid of the lion on the road.' If they say, `Your teacher is within the province,' he answers, `I am afraid of the lion between the ways.' If they say, `He is in your house,' he answers, `If I go to him I will find the door locked..."' We see, then, that it is not fear which leads to laziness, but laziness which leads to fear.
Meaning that the two factors are really one.
at the end of the chapter he writes:
QUOTE
The foregoing discussion of Zeal, I trust, will suffice to awaken the heart. He who is wise will wax wiser and add to his wisdom. Zeal, it should be noted, is appropriately placed a level above Watchfulness; for generally a person will not be Zealous unless he is first Watchful. One who does not concentrate upon being Watchful in his deeds and upon considering Divine service and its principles (such concentration constituting the trait of Watchfulness, as I have already written) will find it very difficult to cloak himself with love and yearning for it and to be Zealous with longing before His Creator; for such a person is still immersed in bodily desires and subject to the inclination of his habits, which draws him away from all this. However, after his eyes will have opened to see his deeds and to be Watchful of them, and he will have made the accounting of good deeds against bad that we mentioned, it will be easy for him to depart from evil and to long and be Zealous for good. This is self-evident.
Which seems to answer the question we had previously if watchfulness has to come before zeal or if both have to come together.

But we'll see if this continues, my laziness is a tough foe.
