Plutarchus's biography of Cato the Elder is the obvious place to begin the search at:
Still, it appears that the people approved of his censorship to an amazing extent. At any rate, after erecting a statue to his honour in the temple of Health, they commemorated in the inscription p359upon it, not the military commands nor the triumph of Cato, but, as the inscription may be translated, the fact "that when the Roman state was tottering to its fall, he was made censor, and by helpful guidance, wise restraints, and sound teachings, restored it again." 4 And yet, before this time he used to laugh at those who delighted in such honours, saying that, although they knew it not, their pride was based simply on the work of statuaries and painters, whereas his own images, of the most exquisite workmanship, were borne about in the hearts of his fellow citizens. And to those who expressed their amazement that many men of no fame had statues, while he had none, he used to say: "I would much rather have men ask why I have no statue, than why I have one." 5 In short, he thought a good citizen should not even allow himself to be praised, unless such praise was beneficial to the commonwealth. [19(3)]
I couldn't find the second one though in a quick search.

The second "quotation" appears in substantially the same form at least twice in the Bible (Prov. 25,6-7; Luke 14,8-9). This does not mean that Cato did not say it as well, but it does raise doubts.
