Making a fresh application after failed previous application

Hello Everyone,

I made a Tier 1 entrepreneur application in Dec 2012, the application was declined. I went to the appeal hearing in January 2014. I am currently appealing to the Upper Tribunal for permission to appeal. But I have been advised to make a fresh application which am currently preparing now.

Am making the current application as a team with 50K. I want to ask the following questions since am making the fresh application as an entrepreneur team;

1) Do we have to submit our applications at the same day?

2) How do I inform UKBA that my international passport and other documents are in the first failed application? Should I write a letter explaining this?

3) Do I withdrawn my appeal before I submit my fresh application or after UKBA have send there letter of confirmation - confirming they have received my fresh application?

4) Assuming my direct application to the Upper Tribunal is unsuccessful, how many days do I have to submit my fresh application. Am only asking because I have heard that they make there decision pretty quick and all my documents for the fresh application will be ready at the end of February 2014.

I will really appreciate your reply. And I want to say thanks in advance.
