Printing - I have my photos printed at a local camera shop. They do a nice job printing. Certainly better than what I've seen from places like CVS. I'm sure in Boston there are camera shops that will do a fine job printing. You might also look into local pro photo development places. These folks only do printing and will do a excellent job. There are also some online options that are great. I've never done this because of the cost of shipping, and my desire to get them as soon as possible.
Frames - For mounting I tape the photo to the mat using a couple pieces of photo tape (it's non-acidic, etc). This allows you to easily move the photos to new frames. It also allows the photo and the other framing materials to move mostly independently of each other so that you don't get wrinkling. It's also cheap and easy.
For frames I've been using Frame Destination http://www.framedestination.com/ I get simple matte black metal frames with good white mattes and the UV filtering non-glare acrylic. For photos I like simple frames that let the artwork stand on its own rather than over the top ones with fancy finishes or colors.
I haven't purchased one in about a year or so, but at the time I paid about $150 plus shipping for two 20x26 frames (for 16x20 prints). It's not cheap, but it was less expensive than any local place and I thought it was a fair price for the size and quality. When finished, it looked really good with the B&Ws that I put in there. Color would probably look great also.
Processing - This might be difficult with these photos. Lightroom is excellent. I use it for everything. But these two look like they're pretty over exposed. Even though the processed ones are better, you can still see all the white spots in the that are blown out. It's going to be difficult or impossible to recover those.
I tend to think there are two aspects to photos like these. The first is the emotional connection you have to them. The second is the technical/artistic side of things. It's something I picked up watching my wife and mother-in-law go through my photos. They always gravitate toward the ones with the people they know in them, even if they are technically inferior to many of the other photos. I do the opposite and tend to choose the ones that are technically superior, but probably not to the same extent that a complete outsider would.
For you I'm sure the emotional connection is good because you have a relationship with both of the subjects. On the artistic/technical side of things, they're not quite as successful. The photo of Zoey has a rather awkward composition, it's overexposed, and I think it's not doing a great job capturing her personality. The other photo has more potential. It could use some heavy cropping. This will also help you remove a lot of the blown out areas in the trees. I'll try fiddling with it when I'm back on my other computer.
