If you want to teach in a college, I would do your Assessors Award next (also now known as TAQA I believe) as this will allow you to assess whether a learner is competent in treatments and is valuable to colleges.
DTLLS is something to think about when you have been teaching for a while, as one of the entry requirements is you need to be teaching for 150 hours in an academic year.
If you require any other information let me know, I've been working in FE for years and I've completed my DTLLS too.
