comment Image classification using google satellite images
You could do that, but be careful about having hard and fast rules. One of the issues with classification is that it uses real world imagery; and real world imagery has variation. Setting a RGB value may result in different classes depending on the temporal and spatial location of the image. If you will be using a repetitive location (ie: time series analysis) then you may be ok. But if you are not, or you will be looking at temporal change, then you will have to deal with a feature having different pixel values at different times of the year (ie: trees). Also don't forget about clouds, etc.

comment Image classification using google satellite images
That will depend on what you are using to classify. If I assume correctly, you are making your own? You will want to look at the pixel values of each band. But you may want to do a neighbour search (3x3, 5x5, 7x7, etc.). Object oriented classification looks at the direction, orientation, proximity, and other aspects of pixels.

comment Is it possible to embed a Qgis map with all the information I added, in my website?
Look at CartoDB. I have a free account with them. You are limited to the number of layers you can show on the free web map. cartodb.com/signup Signup and you will default to the free account

You will be able to use QGIS to make some of the data. I have used MapBox and CartoDB to do this very thing. I found that GeoJSON is the best data format for web maps such as MapBox and CartoDB.
