But yeah, power leveling smithing won't do a lot of good unless you have access to the raw materials required to make higher level armors (unless you want to go all the way to 100 and make dragon armor, for which you can easily find raw materials)
Speech, on the other hand, is causing me a lot of grief. I know life in Skyrim would be alot easier if I were richer, but I simply am not making enough money because my speech skill is at about 29 (level 13) and am just not getting good bargains on all the loot from plundering. I haven't even gone for the 5k house yet (just storing my spare items in the Companians Dorm in Whiterun and checking on them regularly to make sure stuff doesn't dissappear).
