Tl;dr
1. Vitamin d supplementation is generally a good thing
2. Preliminary results indicate risk/reward of vitamin d concentration levels in the blood
3. Too little, bad. Too much, bad.
...how much vitamin d is needed to reach "desirable" levels, who knows? Will vary person to person for a whole host of reasons. Trial and error with some individual bloodwork could help...if you're that concerned...

Theres research indicating that there are benefits of higher Vit D serum levels (60-80 ng/ml). IIRC ~1000 IU's of D3 (the more bioavailable form) equates to maintaining about 10 ng/ml serum concentrations..I had vit d deficiency (16 ng/ml). I supp'd with ~8000 IU's of D3 and brought my levels up to 70 in about 8 weeks.

It may have helped you, but that's a costly and illogical amount to take. I take 5,000 iu every other day and feel great. Some weeks I skip it just to mix things up. In my experience, 5,000 just makes me feel less healthy in the scope of numerous health domains.
