Log shipping and log chain

Hi guys I have a couple of quick questions about log shipping.I have set up a quick example on our test box and so far as I can tell the process goes something like:1) Create full backup of DB2) Restore DB on secondary server3) Every X minutes take log backup from server 1 and restore on server 2A couple of questions here. First) We do a full backup of our DB every Sunday, and then a log backup every night until the next Sunday to enable point in time recovery. Will the fact that the log shipping is doing log backups and then deleting them after x amount of hours break our maintenance plan log chain? Will this stop us restoring to a point in time?Second) How does the restore on the secondary server work. Does it drop the database on secondary, restore from the initial bak file and apply the log backups. If this is the case would the restore time on secondary get out of hand after a while (i.e after 2 weeks you have to restore 2 weeks worth of log files created after the initial .bak file)??Any help would be great.
