Basic questions for ballpark selection:
Will you hit more HR than you give up? If so, choose a +HR park. If no, choose minus. If you don't know, somehing near neutral.
Are doubles way above average? If so, a big + for 2B. slighlty above average doesn't mean much. if below average then -2B.
Is this an extreme triples team? choose an extreme 3B park. otherwise 3B is less significant, there just aren't many triples.
choosing 1B involves several factors. High average low OAV teams do better in +1B parks. Fatigue is a major factor, if you expect fatigue problems then choose a pitchers ballpark no matter what. Speed teams do better in pitchers parks because speed is more valuable in low scoring games. minus 1B parks are somewhat favorable for teams with very high walks and low BB/9, but if you're close to average this factor is insignificant.
