Does an urinalysis report of: leukocyte esterase 1+, urine WBC 6-10 and squamous epithelial cells 0-5 mean an infection?

Not necessarily. Voided (vs. catheterized) urine specimens in women are potentially subject to contamination. Urine culture is the definitive method of determining the presence of infection. Another important point is that in older women in the absence of symptoms, this kind of urine abnormality alone or even a positive culture should not be treated with antibiotics (asymptomatic bacteriuria).
