求求大家了，指点我一下吧！

我现在已经拿到了Dalhousie的Master of e commerce的admission了，读两年。我本身是计算机的硕士。因为不想读计算机的PHD了，所以申请了这个跨学科的专业。我个人来说比较喜欢。
现在在准备签证，前几天从加拿大的大使馆下载了STUDY PERMIT APPLICATION KIT。有些地方不太明白，想向您请教：


在Financial Support这部分里，有如下几句话，我理解的不太顺畅。
In order to establish financial ability to support your studies, family
banking records must be submitted for funds that
show a history of at least 18 months. In order to demonstrate this, we
require the following:
1）original Certificates of Deposit dated within the last 2 months
showing current funds available AND
2）original deposit slips and/or original bank passbooks AND
3）a written explanation of the source of funds.
family banking records must be submitted for funds that show a history of at least 18 months。意思是不是说家里的存款必须要存至少18个月才可以吗？如果已经有了20000元的存款，并且也已经存了18个月，再往里存8万可以吗？这10万元算不算合格的呢？
If you are employed, submit:
   1 original letter of employment (see details below)
   1 original letter of employment from the current employer of each
parent including: full name, address and telephone number of
the parent’s employer; parent’s length of service, position, salary for the last two years, any bonuses and additional income. If you are being supported by a person other than your parents, the same information is required for them.
这几句话是什么意思？？现在对于财产证明的问题，我还十分糊涂，父母资助我读书，我应该做些什么呢？
    我是计算机专业的硕士，高中的学历证明和成绩还要吗？您觉得申请签证的过程中什么最重要？应该注意些什么问题？
如能及时答复我，将万分感谢！在这里先谢过了！！！
