This is a question of precise calculation mostly. Principles to follow:
1) Take all free VP you can and calculate exactly how much it will make in the particular month - take care, numbers for different months will differ!
2) Calculate the lacking amount.
3) Search for the cheapest and most useful alternative to get these VP. Maybe TCredits are best. If you choose them, don't be irrational and don't buy them by 1. Next month will come and they come handy.
4) Take all opportunities you have - games and auctions, bonuses etc.

Sorry to say, Standing Order is most convenient, but suboptimal from tight budget point of view. You may win VP or auction and that will make the whole picture different.

Hope it helps.
