Bottom Bracket/General Frustration advice please?

Prior to Xmas I bought a new bike at a shop which is not my LBS but
nonetheless seemed ok. I wanted a second bike for general buggering about
on. They were selling it quite cheap whereas my LBS has a reputation for
being rather pricey.
However, having now done a good few hundred miles on it I have noticed
that
the shifting, particularly at the front, continues to be very hit and miss
and the bottom bracket creaks like hell, which is driving me absolutely
nuts. I initially put the shifting down to general cable stretch and duly
took it back to the shop (3rd time) where I bought it who inform me that
they again adjusted/stripped it all and that the creaking was due to the
aluminium/steel relationship between frame and bracket and that this was
normal. They have now made 3 attempts to sort it out and its no better.
The
set is Tiagra and it generally starts after about 10 mins riding - hence
the
fact it doesn't happen on the stand or outside the shop!!
With the above characterisics I'd suspect a loose crank-to-ring bolt. They
creak, can affect shifing, and when you let it sit the oxide will build up -
starting off there's no creak, then the oxide rubs off and it does.
