The maximum rating of the fuse should be the no higher than the rating of the cable it is protecting. You can have less if you want, just make sure that it is more than the current needed.
Keep the fuses in the distibution block and make sure that the cables supplying the amp and inverter are no thinner than 10awg. 8awg would be good.
No, this is not too much fusing. It's exactly right. The inline fuse and the fuses in the distribution block are to protect the cables and are meant to blow if the current draw exceeds the ratings of the cables (for example if they short) otherwise they will overheat and catch fire. The fuses in the components are to protect them.
