Cool. Sounds good.
The things to keep in mind with caps generally and especially the Rorqual is that jumping uses cap - and that to make a jump requires a minimum amount of cap (affected by Jump Drive Operation).
It starts at 95% capacitor and can come down to around 70% at lvl 5.
The cap recharge rate is pretty slow on the Rorqual (65 mins recharge without mods) - hence the need for the Capacitor mods and hence the converse that one of your greatest risks is Nuets/Vamps from hostiles. Without the Cap Shield booster active you've a regen of about 250 cap/sec - with the Shield Booster running you've only a net gain of 25 cap/sec.
The largest non-faction neut will drain 25 cap/s - which on a specialised ship (curse) maxes @ 50 cap/s.
In terms of defence then a mixture of drones is your best option. While you can fit smartbombs - you're looking at a max range of approx 10km with officer (and hence expensive) ones. You'll also run the risk of popping your own drones. Yesterday I had an interceptor (crow) webbing me and orbiting at 10km (outside the range of SB's). I tried T2 Med without luck on it - he was moving too fast - so I've gone with the short range sentries (T1 at the mo) which I hope will work better. The T2 med drones did eat nicely into the Cruiser that was also having a go at me

I didn't see what/if any dmg that was done to the (hac I think) that was there (I was kinda busy at the time). I'm also looking to carry some SW-900's (I didn't have any on hand at the time) which I think will also help but 5 of them will only drop a crow running a 4k/s to 1310k/s - handy only really if you've support on site that can stop any hostiles warping.
I think the sentries might work - but I'm worried that they won't be able to track something like the crow without setting them up first at range.
Something I need to test

The Cap Shield booster with the Shield Boost Amp will give you around 7800 a cycle (780/s) - again helpful and most use when you have a small number of hostiles around. One of the hostiles yesterday (the ship I can't remember) was fitted with faction cruise (kinetic) and was hitting me for around 550/missile - which sounds like a lot until you consider that the rof for T2 cruise launchers is 17s (before skills and mods).
Factoring in skills and more launchers (5) and you're looking at around 2500/volley (10s) which can be tanked easily.
The main reason I was down to 85% shields yesterday was mostly due to the NPC's in the belt being BS's
