请问175elodge之后的四个文件

Before you exit you will need to complete the following steps:
   General Skilled Migration Document Checklist (required)
   Attach documents (recommended)
   Retrieve and print your application form (recommended)
   Retrieve your payment receipt details (recommended)

我扣款成功后，网络不稳定，没有点击保存这四个文件。后来再连接就没法下载了。
请问这四个文件重要吗？
前两个每个人都是一样的吗？
