How bout WinXP SP1a.Which should i slipstream?is SP1 the same with SP1a?

Sorry if my question is kinda stupid@silly.I want to know,if i got WinXP SP1a retail Original CD, which hotfixes and updates should I slipstream?I follow the details from GM website and get all the listed HF and Upd. After all the slipstream I install the ISO.The problem is, the installed OS is very slow at winlogon screen(list of user account appear).It takes about 3 minutes to load with just the Admin. account installed no account created.I also sometimes got RUNDLL32.DLL error message, LUNA Styles corrupted.My Quicklaunch missing from its spot and NO THEMES.What happened?What i've done wrong?
