3 UnrealEngine RUNTIME doubts

[Capablanca]

I´d like to produce a walkthrough project about my own house...

I read in UnrealEngine license that i can use the UnrealEngine Runtime (i cannot make a game, but I can make a walkthrough without COMMERCIAL use - i want just distribute it for friends).

So, i have 3 questions:

1) Must I use UnrealEd to do all things? If so, can i use all UnrealEd resources to use in my own house project?

2) I´d like to do a stand alone application (so people could execute my project). What must i do? I can do this just with UnrealEd?

3) Finally, , do you know any TUTORIAL made spefically for UnrealEngine RUNTIME projects?

Thx. for now.
