Harmonic theme related questions

Hello,

I’ve started using the Harmonic theme but I have some questions about it.

I’ve read the « setting up you front page » but that was not enough to resolve my problems.

Two questions:

1. When I activate the theme, a section « Homepage » is automatically created in the menu, referring to my blog address.
To create the front page, I have created a new « homepage » page instead of the previous one, but it now refers to http://www.myblog address/homepage. I would like the homepage (=frontpage) to be linked directly to the main address. I can modify the address from the page section but it automatically modified it to www…./homepage. Any ideas ?

2. I would like to create a slide show in my front page with a possibility to go to the next picture by clicking (on a « next » button for example). Do you know how I could insert it ?

Thanks in advance !

The blog I need help with is mezameyobacchus.net.
