Step 1: Adventure Mode:
Simply play through adventure mode. This will unlock "Home Land Security." This should take a few hours to complete. "Soil Your Plants" and "Crash of the Titan" will unlock during your playthrough aswell. Remember once you have unlocked the chomper to go for "Nom Nom Nom," and to also go for "Close Shave" once you have got all 5 lines of the lawn, as these are easily done once they first become available as there is no level select to choose the easier levels. You should also try to get "Explodonator" while you play through advneture mode.
Step 2: Versus Mode:
You will need another controller to complete "Versus vs Versus" and "ZFF's 4 Evr." This shouldnt take too long to complete
Step 3: Farming Cash:
You will now want to try and earn enough cash to grow the Tree of Wisdom and to buy all plants from Crazy Dave. You will need a total of $345500 to unlock all plants and buy the Tree of Wisdom, the tree food and all the 9 plants. The best way to farm cash is play the Last Stand mini game, however to unlock this mode you will need to complete 13 of the mini games. Follow this video for an easy way to make cash quickly: (is done on PC but the same principles apply)
This method should take you anywhere from 5-10hrs to get enough cash to buy everything. However while playing you will get alot of plants for your zen garden. If you check on the plants there and sell them once they reach $8000 (or $3000 if they are pool plants/mushrooms) It will take you between 3-5 hours to get enough cash to buy all the plants and tree food.
Alternatively you can grind plants for your Zen Garden. Once you have a full set of 32 plants, you can disconnect your console from Xbox LIVE and change the date to the next day, so you don't have to wait until you can water/seed your plants again.
After changing the date 3-4 times, I've reached the final stage. Now you could farm coins, which are dropped by the plants or you could just sell all of them in order to gain about 240,000 bucks.
Step 4: Survival Mode:
This will take the longest to do. You will first need to unlock Endless Survival, which is done by completing all the other survival challenges. Once these are done you will then need then reach flag 40 of Endless Survival.
https://hubpages.com/hub/Plants-Vs-Zo...ags-and-Beyond shows some good was of getting upto wave 40 and beyond.
You should now have all the achievements for PvZ. However there are still loads more to do in this game, such as challenges, zen garden, minigames, find the Zombie Yeti etc.
