I wouldn't buy books just to buy books.
Look at what you want for your game. Look at what is out there. Then decide if it is worth it to purchase more books and which ones to purchase. Read through the reviews section here on ENWorld, they're very useful, and then flip through them in the store. If you think it would add something to your game, and you're in the market, go ahead and buy it. But, they definately arn't a necessary addition.
Converting old material depends on the material, but mostly its pretty simple. There weren't a whole lot of changes from 3.0 to 3.5, really, so its not like you're converting 2E material to 3E in complexity.
