Your plants would do better (and your tank would probably look nicer, although I guess this is personal opinion) with a broader spectrum white light (6700K for instance.) Cycling will proceed with or without plants (most feel that most of the "seeding" beneficial bacteria come in via the tap water, albeit in low numbers, but its not inconceivable that a few extra "seeding" bacteria might come in on plants.
The usual concern about plants is that the high and variable levels of ammonia in a fishless cycle can potentially do two negative things to plants: it can cover them with algae (which can sink anchoring filaments between the plant cells) and in a few cases the plants might be adversely effected by the excessive ammonia level. One approach to this problem is to obtain cheap plants (bunches of elodea for instance) that one would not mind trashing after the fishless cycle.
Another approach to fishless cycling is to wrap the tank in layers of black plastic, taped on for instance, in an attempt to completely block the light that algae would need to grow. This would hopefully guard against algae on the substrate as well as other things, as substrate algae is another problem of fishless cycling in many cases.
