Is a preamplifier needed for antenna reception?

I am very new to the forum. Wanted to get PBS for my little one. Thanks to the experts opinion here, I bought a Clearstream5 antenna. Also bought a distribution amplifier (CM3410 / PCT 1 port distribution amplifier with passive return). My reception report is:
http://www.tvfool.com/?option=com_wr...de6537d4273424. Also see the antenna point report attached.

Currently I have:
C5 antenna trial position at 5 feet from ground -> 40 feet coax cable -> CM3410 distribution amplifier -> 40 feet coax to TV

With this setup, I get all the green color channels including PBS kids. Disconnected Dish and my little one is happy to see her favorite programs. Before adding the distribution amp, the channels were not stable and picture was grainy and went away after some time. With the CM3410 amplifier the green channels are stable. I also bought a) TII 212 Broadband Cable TV Lightning Surge Protector Ground Block and b) 40 inch J-mount, but planning to install them when the cable is run for roof.

I need to fix the antenna at roof (with install help). When I do that, my cable length will increase to 80 to 100 feet before CM3410 amp. The new setup will be C5 antenna at 20 feet -> 100 feet coax cable -> CM3410 distribution amplifier -> 40 feet coax to TV.

My questions to the experts are:

** Do I need to buy Antennas Direct CPA19 pre-amp as I am increasing the cable length by about 60 feet? I think it is better to use same company equipment.
** When I increase the height, add a pre-amp will I gain or lose any additional channels? What can I expect by adding a pre-amp?
** Where do I buy about 100 feet of coaxial cable. I may need to cut the cable with coaxial connection attachment. Crimper tool for one time use?
** I am also not sure where to add power to the pre-amp? Do I need to run another 100 feet cable to the antenna and then get output from the preamp close to the antenna? Are there any smarter alternatives?

The one installer that I spoke to wanted about $250 for labor and another $125 coax and ground. I am thinking of getting handyman help to only install it on the roof and depend on experts advice here for technical advice.

This whole exercise is challenging and confusing. But I am willing to struggle to get it right one time and forget about it (hopefully for a few years). You suggestions are very valuable.
