Very comprehensive set up for starters.
You have a steep learning curve - get a book. The old standard was the 35mm handbook - the principles still hold true. A book on photography can be found in most
second hand bookshops. OR go to one of the remainders shops around the place - even the most basic book will help you in your first months of learning - as will the camera manual. Read it from cover tocover.
Your first thing to understand is the longer your lens, the faster the shutter you need to make a sharp picture - to get a fast shutter you need some light...indoors there is little! That is why your pics were blurred, it is called "camera shake".
Use a shutter speed, NO, make sure you have a shutter speed equal to the legth of lens in use when hand holding. If you can support the camera, by leaning against a door frame for instance (or putting it on the table, or a tripod) then you can use a much slower shutter speed. With the 10mm you shgould be abe to hand hold it and get acceptable results down to 1/20th sec. More experienced folks will be able to hand hold that same lens to 1/6th, and leaning aganst a door frame probably 1 sec.
With a longer exposure, anything that moves while the shutter is open will be blurred - it takes that length of time for the image to "burn" onto the film or sensor.
Enough for one go, other wise you will get overload.
