Oh its fine I'm always happy to recommend books. Really it depends on what area you need help on. For instance, I'm mainly using the Antonia Fraser biographies on Charles II and Louis XIV, and for government,Restoration: Charles II and his Kingdoms by Tim Harris. For general period sources, I'll have to look around.
Thank you. Basically its a Lord Protector TL, though with a unique POD during the Civil War. The Civil Wars themselves continue without much difference, however it butterflies into a change of succession on Cromwell's death. The way things are going its looking like a Forth Civil War (thus I'm trying to find numbers for how many soldiers would be active at any given time), and probably a continuation of the Spanish War (and I'm looking at the viability of a Portugese-English alliance against Spain.
Problem is Portugal still recognises Charles II as King. It has done deals with the Commonwealth though. One big question is if it would be prepared to sell Charles II out for support against the Spanish, or if they'd continue to fight on alone. Since the English deployed 3,000 Veterans to Flanders I see them deploying a larger force into Portugal though possibly with the restraint of 'protecting Portugal's independence' and prevented from using Portugal as a staging ground for a full scale invasion. However numbers again would be a factor).
Plus I still have no idea how I'm going to deal with the Dutch problem. Still very much a work in progress but any relevant books/texts will help refine exactly what happens. The pieces I've found so far tend to lack the fine mechanic details, more referring to common well recorded events and conjecture about states of mind. The Louis XIV book sounds good though, it will help plot France's decision making (though I suspect it will be very similar to OTL given how England will be more fixated on finishing the Spanish war. With the Treaty of the Pyrennes France is doing rather well and Louis XIV will probably be happy to let England and Spain slug it out). Worth a read though.
