I am planning to buy as micro lens to shoot tiny objects, i am confused which one to get, Tamron 90mm f2.8 micro or sigma 105mm f2.8 micro.
plz suggest me.

And one thing more can i put micro filters to that lenses to get further closer to object. and wht will other methods to reduce focusing lenght of lens.

plz also suggest wht other care i should take while buying the same.

The 105 will allow you to work at slightly greater distance to have the same level of magnification. That can be useful if you are photographing subjects that may be disturbed by the lens being very close.
Both are very good lenses so it really comes down to personal choice and possibly price.
When you ask about micro filters I presume you mean close-up lenses that screw into the front of the lens in the same way that filters do. I'm not sure whether on not they would be very successful, but they will reduce image quality.
Finally - it is a macro lens, not micro.

Both lenses are very good and fits your need, but I would choose sigma.
