No.
These two options are OK.

If you are going to succeed in (your) life, you will need lots of confidence.
If you are going to succeed in (your) life, you will need to have lots of confidence.

The "your" is not necessary.

Right. You can say:

- "you will need confidence.
- you will need to have confidence.
- you will have to have confidence.

But "have to need" doesn't make sense.
