Hello Spdrcr5,
I'm sure you're read many of the opinions regarding attic installations here. We often frown on them because before you even do your first channel scan you are putting your antenna in a potential hostile reception situation.
Further, attic installations can also cause green signals to not be reliable due to multipath or interference from household electronics.
Answers to your questions:
1. See below.
2. No preamp.
3. Others might have advice here.
4. See below.
5. With my recommendation a mast is the better choice. You could even use something like this:

If the attic is your intention, no I would not use a HBU 22. Generally if you are going to install an antenna in attic you need an antenna 1 to 2 notches better than what your TV fool report calls for. This is to offset the attic conditions.
If I were doing this set up in the attic, I would do a two antenna set up. The first antenna would be a
Antennas Direct DB8e. This antenna allows for independent adjustment of each panel to a its own heading. First panel orientate to magnetic heading 314. This will provide coverage for KADN, KATC and KLPB. Second panel of DB8e orientate to magnetic heading 73. This will provide WVLA. As a bonus, you should also see from the second panel WGMB FOX.
You'll notice you have a mixture of real channels 7-13 and 14 and above. This means you have high-vhf and UHF signals to plan for.
The DB8e tends to your UHF requirements. The second antenna, a
AntennaCraft CS600 is a suburban VHF only antenna. It does real channels 2-6 and 7-13 only. I would use this antenna for KLFY CBS real channel 10. Orientate this antenna to magnetic heading 307.
You need a signal combiner. This in effect allows two antennas to be combined into one lead. The
Pico Macom UVSJ UHF VHF Band Separator/Combiner at this time appears to be the only quality unit on the market that accomplishes this. Connect to DB8e jumper coax to UHF connector, connect CS600 jumper to VHF input. Run coax lead into home.
You might think this is a bit more than you expected. Generally with attic installations going up a couple notches in system is a good idea. It gives you a system that has enough extra strength to work in an environment where line of sight is not available.
Cheers.
