Looks like it's already indented enough to me
But seriously, it sounds like you got a good price on what may have potential to be a good bass. There can be a lot of $ range between what it takes to make it playable and a full restoration and only you and your bank balance know how far to take it. If it was mine, i'd be tempted to do just what it takes to make it structurally sound and playable and leave the bumps and bruises.
BTW, Violen, my ebony board looks a lot like that ... kind of grayish on the end grain that hasn't been polished.
