Instead of TMH i think you should do HC Verma fully .. all problems . all theory everything at all!!..if you feel it is too easy go for DC Pandey for slightly higher level problems.
Its always a good ideal to get the study material of a reputed institute.
FIITJEE GMP is the best i think.

You can keep RH for fun, it is very easy...when you are bored and have nothing to do then you can go through the therory in RH and also some problems .. it is a lot of fun and is beneficial too.

Also I think Resnick Halliday and KRANE is a better book than WALKER, see if you can get it changed, if not WALKER is good too.
