No reason you can't shop their website, use their fit guide, and then order that stuff local. I did that. Crurchfields Master guides are just a nice to have for anyone that's never done a radio/speaker upgrade before.
Update the speakers alone is the biggest improvement for the lowest cost, the stock head units are not shabby (Alpine). Because my '07 didn't support for aux/MP3 I did head unit and all four speakers with steering wheel controls adapter. Having four speakers in the 5 means you can get by very well with just a head unit with 25Wpc and decent entry/mid full range Pioneer/Kenwood speakers. I leave my door tweeters disconnected.
Cabin lighting to LED is a huge difference. The interior trunk light has an odd mechanism that makes LED not viable.
Putting on real fog light bulbs, yellow ones, is worthwhile if you see foggy/cloudy conditions enough.
I see you have sidesill/rocker panels but no rear mudflap. That's something that always irked me - no mudflaps for models with rocker trim. Gonna look into that and see what the options are.
I did rack/box add too.
