Dear sir,
1. Translate:
Please go to admin site: Settings-> General and change your language to your language.
After go to folder: wp-content/themes/your_theme/lang, you can see .po or .pot file.
If there is .po file please copy it and change to your language file and translate by POEDIT (after translate click save file to convert to .mo file).
If there is not .po file (only .pot file) please open it by POEDIT click Create new translation to create .po file, open .po file to translate.
Woocommerce: Please translate in wp-content\plugins\woocommerce\i18n\languages
2. Icons: Please input images in admin site: Products-> Categories, add images in each product which you chose in this element.
3 . Menu: Refer here to fix this:
