I used to live in Somerville near Davis Square and in East Arlington. I liked the Minuteman trail.
Ball bearings for hubs are fairly standard. Rear wheels nearly always take 1/4 ball bearings, 9 on a side. The bottom bracket will take 1/4 ball bearings 11 on a side if running loose; with a cage you may have fewer (usually around 9). The front hub is generally 3/16 ball bearings 10 on a side. There are some exceptions but you can google the name of your hub to see if your hubs are a bit different.
I wouldn't sweat overhauling the freewheel. You will want to drizzle some oil to help lubricate it. You will want to overhaul the headset also and hopefully the ball bearings are in a race as that will make your life easier.
Wheels manufacturing grade 25 ball bearings are the way to go (or any grade 25 ball bearing from a reputable source)
