All you really need is a spring compressor and normal hand tools (and a big-ass breaker bar if you don't have an impact, as the suspension bolts tend to be pretty seized up). You can rent a spring compressor from vato-zone for like $10.
As for the Gabriel brand... I've never heard of it, which makes me guess that its just some generic OEM replacement brand, since I've been doing this honda stuff for 6 years.
