Unless you have fully synced all other story missions, you will need to re-do them and complete them to 100%. Including the DLC. You can earn Airstrike in the DLC mission "A Roll of the Dice" since there are exactly 10 guards right in the beginning of the mission. Head to the Thieves Guild and earn 10,000 florins for the High Roller achievement. Grand Theft Dressage, Special Delivery, Clowning Around and Strong-Arm are all miscellaneous achievements that can be completed whenever. Going Up and Easy Come, Easy Go are both extremely easy which can both be completed in 5 minutes.
Conclusion:
You should have all single player achievements by the end of the game. When you're done, just grab the last of the collectibles and anything else you may have passed on for later. Multiplayer will take some time to boost, but if done efficiently you will have this game completed without too much effort. The only part that could be troublesome is finding good people to boost with that will be committed.
