Are pride and boasting ever okay? We are proud of our son for being able to write his name, and my wife was boasting that she helped him learn to write it.  Ultimately, we both know it's from God that he is able to learn this skill and my wife has the ability to teach him.
I know that pride and boasting in ourselves is not good (see verses below), but as long as we ultimately acknowledge God in our pride and boasting, is it acceptable to do this?
Jeremiah 9:23–24 (NIV)

    23 This is what the LORD says:
    
      &nbsp;&nbsp;&nbsp; “Let not the wise boast of their wisdom 
       &nbsp;&nbsp;&nbsp;or the strong boast of their strength 
       &nbsp;&nbsp;&nbsp;or the rich boast of their riches, 
    24 but let the one who boasts boast about this: 
      &nbsp;&nbsp;&nbsp; that they have the understanding to know me, 
    that I am the LORD, who exercises kindness, 
      &nbsp;&nbsp;&nbsp; justice and righteousness on earth, 
       &nbsp;&nbsp;&nbsp;&nbsp;for in these I delight,” 
              &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp; declares the LORD.

James 4:6 (NIV)

    6 But he gives us more grace. That is why Scripture says:
    
      &nbsp; &nbsp;&nbsp;&nbsp;“God opposes the proud 
     &nbsp; &nbsp;&nbsp;&nbsp; but shows favor to the humble.”
To supplement your verses on proper/inproper boasting, see Phil 3:4,7-8 and Gal 6:13,14.
To answer your question, I first quote 


  In all your ways acknowledge Him, and he shall direct thy paths
   Prov. 3:6


Especially if you honor God, (as you say "as long as we ultimately acknowledge God") it is good to praise others, or to be satisfied in someone or something, even your own accomplishments. We mustn't, however honor God with our lips while our heart is far from Him. (Isaiah 29:13)

When the Lord saw what He had created and called it good. He was proud of His creation. He called it good. Even to Satan, God says, "Have you seen my servant Job?" and in Zeph 3:17 He rejoices over His people with singing.

If you read the words of many righteous men in scriptures, they acknowledge what they have done with the Lord's help. David did no wrong in 1 Samuel 17:34-37 when he said to Saul


  Thy servant kept his father's sheep, and there came a lion, and a
  bear, and took a lamb out of the flock: And I went out after him, and
  smote him, and delivered it out of his mouth: and when he arose
  against me, I caught him by his beard, and smote him, and slew him.
  Thy servant slew both the lion and the bear: and this uncircumcised
  Philistine shall be as one of them, seeing he hath defied the armies
  of the living God. David said moreover, The LORD that delivered me out
  of the paw of the lion, and out of the paw of the bear, he will
  deliver me out of the hand of this Philistine. And Saul said unto
  David, Go, and the LORD be with thee.
  (emphasis added)


So, your wife can be proud to say with full assurance that she is teaching your son to read. I praise God with you that she has that ability!
