That seems like way too many...
When this additional stuff first came out for iphone/ipod, I have played the earlier version twice and bought everything that could be bought up to that point. I had enough coins to unlock the full Zen Garden and 2 mini-game-packs immediately.
Starting the game with Zen Garden already available, it will be even easier to get enough coins to unlock everything. Just get the Zen garden at the earliest opportunity and tend to the plants there, which is not onerous.
