Restoration of SQL transaction logs

I would like to restore SQL database and roll forward to a specific point in time by applying transaction logs.The backup software used is brightstor r11.5. I have 4 tapes (Tape 1 contains the full database),(tape 2 contains the first transaction log after the full database backup),(Tape 3 contains the second transaction log) and (Tape 4 contains the last transaction log ).How should i configure brightstor to do the job.There are various options in restore manager that’s really confusing.I would really appreciate if the restoration procedure could be provided step by step.Thanks.
