Techincally the achievements for obtaining the special objects are missable but you won't have to redo anything as you can just go back through the level select. All of the achievements for this game are extremely easy bar one which is "Perfect". This achievement may take you a while to get but after an hour or two of trying you should have it. This is also the reason why I have suggested two playthroughs as it would be almost impossible to get this achievement in one try.
Step 1: Playthrough #1
The first playthrough is very simple. Just play through the levels until you get to level 21. Along the way, all you have to do is make sure you you pick up the special objects that appear in each level after eating a certain amount of pellets.
Step 2: Getting "Perfect"
This is the hard part. "Perfect" can be pretty difficult, especially if you're not that great at Pac-Man. If you're pretty skillful at this game then you should have no trouble achieving it after a few goes. If you're not that good then I suggest trying to learn a specific route rather than just moving around randomly. The achievement guide offers a good video and diagram of routes you can take to achieve this.
Overall, this is an easy game with one tricky achievement. If you need further help with the "Perfect" achievement then seek help on the x360a Pacman forums.
