How to Install WordPress with Local Server?

1.Who have successfully installed I created a display Web Blog / Hello World and Dashboard (for setting), can not be loaded again. (After the computer off and on on his back). Should always create a new database again.

2.On page posts and dashboard warning appears:
2.1 Warning: date() [function.date]: It is not safe to rely on the system’s timezone settings.You are *required* to use the date.timezone setting or the date_default_timezone_set()function. In case you used any of those methods and you are still getting this warning,
you most likely misspelled the timezone identifier. We selected ‘Asia/Krasnoyarsk’ for ‘7.0/no DST’instead in C:\\xampp\\htdocs\\wordpress\\wp-includes\\class-simplepie.php line 3579.

2.2 Warning: strtotime() [function.strtotime]: It is not safe to rely on the system’s timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected ‘Asia/Krasnoyarsk’ for ‘7.0/no DST’ instead in C:\\xampp\\htdocs\\wordpress\\wp-includes\\default-widgets.php on line 818.

3. WordPress-2.8.4 Install the Web server via FileZilla FTP uploads. Never succeeded even though I’ve changed the file wp-config-sample.php into wp-config.php file (including changing its content in accordance with the instructions WP).

4. How the next solution, so that I can easily use the WordPress WebBlog is good he is?
