Neither of these things tell you much.
Placement into competitive residencies: while a high number is encouraging, a low number isn't necessarily bad. After all, since you don't know how many tried to match into competitive residency X, the raw number is relatively meaningless.
Location: again, difficult to say whether or not this is helpful. Many people choose residency location for family reasons (ie, couples matching), for geographical reasons (ie, want to be close to family, certain area of country, etc.), etc. Also remember that the big names aren't necessarily the best places for certain residencies. There are many more prestigious and competitive FP residencies than those at some of the Ivy League schools.
Most medical schools boast a decent match percentage. If you ask them how many of their students in each specialty matched into one of their Top 5 programs, that *might* mean more, but again it tells you little about the competitiveness of the student, the programs they applied to, etc.
Unless you saw some glaring inadequacy, I wouldn't make it a significant factor in choosing a medical school.
If you might possibly be interested in a competitive residency, you might, however, be well advised to choose a medical school which has a strong department and residency in that particular field. It might be helpful come match time.
