Strong preference for longer itineraries. A week is much too short, 10-12 days works.Given your thoughts here, I assume 12 days would be preferable to shorter itineraries as well.
A liveaboard will cover most of Raja giving you a sample of each area while land based will give you more sites in a limited part of Raja. Neither is intrinsically better, just different. For your first trip I would do a liveaboard as you get a little bit of everything.
I like to do 2 - 4 days somewhere else in Indo before RA to get over jet lag and dial in my diving before getting on a liveaboard. Bali and Lembeh both work. Not always possible, but I find it takes at least a couple of days to change time zones and doing that on a liveaboard is expensive.
