do I need the standard lens?
Answer
Funny, somebody asked this 2 days ago about the 450D...
My answer then and my answer now is that the 50mm is terrible as a walk around lens on a cropped sensor. It´s nice for portraits, but not recommended as your only lens.
Get the 18-55mm zoom. It´s a consumer grade zoom that will do nicely unless/ until you can afford to jump to the $500 mark. In that case get the Canon 17-85mm zoom or the Tamron 17-50mm f/2.8. (Or if you want bling-a-ding pro results, save up for the +$1000 Canon 17-55mm f/2.8)
The 50mm f/1.8 does indeed have marginally better image quality than the 18-55mm zoom, but the 50mm will only be useful for 5% of your intended shots.

im looking for one good prime lens that will get the job done no matter what the job is !
Answer
There really isn't any such thing as a single lens - prime or zoom - that "... will get the job done no matter what the job is!" That's why Canon offers so many different lenses. For some, the
EF-S 18-200mm f3.5-5.6 IS is a good "walking around" lens when out on a day trip. Indoors its not so good a choice since its a slow, variable aperture lens. Someone else might prefer either the EF 24mm f1.4 II USM or the EF 35mm f1.4L USM for a "walking around" lens. Either of these fast lenses will prove useful indoors in low-light. The EF-S 17-55mm f2.8 IS USM might be someone else's choice.
Usually the idea when shooting portraits is to achieve a shallow DOF to create separation between your subject and the background. On a 35mm film camera or full-frame DSLR a focal length between 85mm to 105mm would be considered the ideal portrait lens. With the 1.6x "crop factor" of your 7D a 50mm lens would have an equivalent angle of view of an 80mm lens on 35mm of full-frame and would be a good choice for portraits.
When shooting landscapes the idea is to achieve maximum DOF and that's when a wide-angle lens is used. The EF-S 10-22mm f3.5-5.6 USM would be a good choice.
The idea is to choose a lens based on what and where you're shooting.
