new yaris owner,need suggestions re. noise

[yandpfan]

Just purchased a 2008 yaris,barebones, 2 dr...after driving a prius for 11yrs. If I want to try to reduce road noise should I start with the hood or trunk and front wheel wells or elsewhere? It would be a diy project, I'm not mechanically inclined, but I do quilt and sew, and some videos I've watched seem to recommend a pieced, layered approach as possibly superior for more inexpensive sound deadening. Would welcome advice re. best products and if I can't do whole car, most effective areas to tackle first. Thanks in advance.
